GENERAL DESCRIPTION
All devices fully conform to the EIA-232-E and CCITT V.28
specifications and operate at data rates up to 230 kbps. Shutdown and enable control pins are provided on some of the
products (see Table 1).
The shutdown function on the ADM211E disables the charge
pump and all transmitters and receivers. On the ADM213E the

The ADM2xxE is a family of robust RS-232 and V.28 interface
devices that operate from a single 5 V power supply. These products are suitable for operation in harsh electrical environments
and are compliant with the EU directive on electromagnetic
compatibility (EMC) (89/336/EEC). The level of emissions and
immunity are both in compliance. EM immunity includes ESD
protection in excess of ±15 kV on all I/O lines (IEC 1000-4-2),
fast transient burst protection (IEC 1000­4­4), and radiated
immunity (IEC 1000-4-3). EM emissions include radiated and
conducted emissions as required by Information Technology
Equipment EN 55022, CISPR 22.

Figure 1.
charge pump, all transmitters, and three of the five receivers are
disabled. The remaining two receivers remain active, thereby
allowing monitoring of peripheral devices. This feature allows
the device to be shut down until a peripheral device begins
communication. The active receivers can alert the processor,
which can then take the ADM213E out of the shutdown mode.
Operating from a single 5 V supply, four external 0.1 μF
capacitors are required.
The ADM207E and ADM208E are available in 24-lead PDIP, SSOP,
available in 28-lead SSOP, TSSOP, and SOIC_W packages. All
products are backward compatible with earlier ADM2xx products,
facilitating easy upgrading of older designs.

Transmitter (Driver) Outputs. These are RS-232 signal levels (typically ±9 V).
Receiver Inputs. These inputs accept RS-232 signal levels. An internal 5 kΩ pull-down resistor to GND is connected on
each input.
Receiver Outputs. These are TTL/CMOS output logic levels.
Receiver Enable (active high on ADM213E, active low on ADM211E). This input is used to enable/disable the receiver
outputs. With EN = low for the ADM211E (EN = high for the ADM213E), the receiver outputs are enabled. With EN = high
for the ADM211E (EN = low for the ADM213E), the receiver outputs are placed in a high impedance state. (See Table 3
and Table 4.)
Shutdown Control (active low on ADM213E, active high on ADM211E). When the ADM211E is in shutdown, the charge
pump is disabled, the transmitter outputs are turned off, and all receiver outputs are placed in a high impedance state.
When the ADM213E is in shutdown, the charge pump is disabled, the transmitter outputs are turned off, and Receiver R1 to
Receiver R3 are placed in a high impedance state; Receiver R4 and Receiver R5 on the ADM213E continue to operate
normally during shutdown. (See Table 3 and Table 4.) Power consumption for all parts reduces to 5 μW in shutdown.

THEORY OF OPERATION
All RS-232 inputs and outputs contain protection against
electrostatic discharges up to ±15 kV and electrical fast transients up to ±2 kV. This ensures compliance to IEC 1000­4­2
and IEC 1000­4­4 requirements.
The devices are ideally suited for operation in electrically harsh
environments or where RS-232 cables are plugged/unplugged
frequently. They are also immune to high RF field strengths
without special shielding precautions.

The ADM206E/ADM207E/ADM208E/ADM211E/ADM213E
are ruggedized RS-232 line drivers/receivers that operate from a
single 5 V supply. Step-up voltage converters coupled with level
shifting transmitters and receivers allow RS-232 levels to be
developed while operating from a single 5 V supply.
Figure 21. Charge Pump Voltage Inverter
Transmitter (Driver) Section
The drivers convert 5 V logic input levels into EIA-232 output
levels. With VCC = 5 V and driving an EIA-232 load, the output
voltage swing is typically ±9 V.
Emissions are also controlled to within very strict limits.
TTL/CMOS technology is used to keep the power dissipation to
an absolute minimum, allowing maximum battery life in
portable applications. The ADM2xxE is a modification,
enhancement, and improvement to the ADM2xx family and its
derivatives. It is essentially plug-in compatible and does not
have materially different applications.
Unused inputs can be left unconnected, as an internal 400 kΩ
pull-up resistor pulls them high, forcing the outputs into a low
state. The input pull-up resistors typically source 8 μA when
grounded, so unused inputs should either be connected to VCC
or left unconnected in order to minimize power consumption.
CIRCUIT DESCRIPTION
Receiver Section
The internal circuitry consists of four main sections:
The receivers are inverting level shifters that accept EIA-232 input
levels and translate them into 5 V logic output levels. The inputs
have internal 5 kΩ pull-down resistors to ground and are
protected against overvoltages of up to ±25 V. The guaranteed
switching thresholds are 0.4 V minimum and 2.4 V maximum.
Unconnected inputs are pulled to 0 V by the internal 5 kΩ pulldown resistor. This, therefore, results in a Logic 1 output level for
unconnected inputs or for inputs connected to GND.
•
•
•
•
A charge pump voltage converter.
5 V logic to EIA-232 transmitters.
EIA-232 to 5 V logic receivers.
Transient protection circuit on all I/O lines.
Charge Pump DC-to-DC Voltage Converter
The charge pump voltage converter consists of a 200 kHz
oscillator and a switching matrix. The converter generates a
±10 V supply from the input 5 V level. This is done in two
stages using a switched capacitor technique as illustrated in
Figure 20 and Figure 21. First, the 5 V input supply is doubled
to 10 V using Capacitor C1 as the charge storage element. The
10 V level is then inverted to generate −10 V using C2 as the
storage element.
Capacitor C3 and Capacitor C4 are used to reduce the output
ripple. If desired, larger capacitors (up to 47 μF) can be used for
Capacitor C1 to Capacitor C4. This facilitates direct substitution
with older generation charge pump RS-232 transceivers.
The V+ and V– supplies can also be used to power external
circuitry, if the current requirements are small (see the Typical
Performance Characteristics section).
The receivers have Schmitt trigger inputs with a hysteresis level
of 0.65 V. This ensures error-free reception for both noisy
inputs and for inputs with slow transition times.
ENABLE AND SHUTDOWN
Table 3 and Table 4 are truth tables for the enable and shutdown
control signals. The enable function is intended to facilitate data
bus connections where it is desirable to tristate the receiver
outputs. In the disabled mode, all receiver outputs are placed in
a high impedance state. The shutdown function is intended to
shut down the device, thereby minimizing the quiescent
current. In shutdown, all transmitters are disabled and all
receivers on the ADM211E are tristated.
Rev. E | Page 10 of 20
ADM206E/ADM207E/ADM208E/ADM211E/ADM213E
On the ADM213E, Receiver R4 and Receiver R5 remain
enabled in shutdown. Note that the transmitters are disabled
but are not tristated in shutdown; it is not permitted to connect
multiple (RS-232) driver outputs together.
The shutdown feature is very useful in battery-operated systems
since it reduces the power consumption to 1 μW. During
shutdown, the charge pump is also disabled. The shutdown
control input is active high on the ADM211E, and it is active
low on the ADM213E. When exiting shutdown, the charge
pump is restarted, and it takes approximately 100 μs for it to
reach its steady state operating condition.
HIGH BAUD RATE
The ADM2xxE feature high slew rates, permitting data
transmission rates well in excess of the EIA-232-E
specifications. RS-232 levels are maintained at data rates up to
230 kbps, even under worst-case loading conditions. This
allows for high speed data links between two terminals, making
it suitable for the new generation modem standards that require
data rates of 200 kbps. The slew rate is controlled internally to
less than 30 V/μs to minimize EMI interference.
protection structure is shown in Figure 24 and Figure 25. Each
input and output contains two back-to-back high speed
clamping diodes. During normal operation, with maximum
RS­232 signal levels, the diodes have no effect because one or
the other is reverse biased, depending on the polarity of the
signal. If, however, the voltage exceeds about ±50 V, reverse
breakdown occurs, and the voltage is clamped at this level. The
diodes are large p-n junctions designed to handle the
instantaneous current surges that can exceed several amperes.
The transmitter outputs and receiver inputs have a similar
protection structure. The receiver inputs can also dissipate some
of the energy through the internal 5 kΩ resistor to GND as well
as through the protection diodes.
The protection structure achieves ESD protection up to
±15 kV and EFT protection up to ±2 kV on all RS-232 I/O
lines. The methods used to test the protection scheme are
discussed in the ESD Testing (IEC 1000­4­2) and EFT/Burst
Testing (IEC 1000­4­4) sections.

ESD/EFT TRANSIENT PROTECTION SCHEME
The ADM2xxE use protective clamping structures on all inputs
and outputs that clamp the voltage to a safe level and dissipate
the energy present in ESD (electrostatic) and EFT (electrical
fast transient) discharges. A simplified schematic of the
IEC 1000-4-2 (previously IEC 801-2) specifies compliance
testing using two coupling methods, contact discharge and airgap discharge. Contact discharge calls for a direct connection to
the unit being tested. Air-gap discharge uses a higher test voltage
but does not make direct contact with the unit under test. With
air-gap discharge, the discharge gun is moved toward the unit
under test, developing an arc across the air gap. This method is
influenced by humidity, temperature, barometric pressure,
distance, and rate of closure of the discharge gun. The contact
discharge method, while less realistic, is more repeatable and is
gaining acceptance in preference to the air-gap method.
Although very little energy is contained within an ESD pulse,
the extremely fast rise time, coupled with high voltages, can
cause failures in unprotected semiconductors. Catastrophic

destruction can occur immediately because of arcing or heating.
Even if catastrophic failure does not occur immediately, the
device can suffer from parametric degradation that can result in
degraded performance. The cumulative effects of continuous
exposure can eventually lead to complete failure.

I/O lines are particularly vulnerable to ESD damage. Simply
touching or plugging in an I/O cable can result in a static
discharge that can damage or destroy the interface product
connected to the I/O port. Traditional ESD test methods, such
as the MIL-STD-883B method 3015.7, do not fully test product
susceptibility to this type of discharge. This test was intended to
test product susceptibility to ESD damage during handling.
Each pin is tested with respect to all other pins.
There are some important differences between the traditional
test and the IEC test:
•
•
•
The IEC test is much more stringent in terms of discharge
energy. The peak current injected is over four times greater.
The current rise time is significantly faster in the IEC test.
The IEC test is carried out while power is applied to
the device.
It is possible that the ESD discharge could induce latch-up in
the device being tested. This test, therefore, is more representtative of a real-world I/O discharge, where the equipment is
operating normally with power applied. However, both tests
should be performed to ensure maximum protection both
during handling and later during field service.

There are four levels of compliance defined by IEC 1000-4-2.
ADM2xxE products meet the most stringent compliance level
both for contact and for air-gap discharge. This means that the
products are able to withstand contact discharges in excess of
8 kV and air-gap discharges in excess of 15 kV.

IEC 1000-4-4 (previously IEC 801-4) covers EFT/burst
immunity. Electrical fast transients occur because of arcing
contacts in switches and relays. The tests simulate the
interference generated when, for example, a power relay
disconnects an inductive load. A spark is generated due to the
well-known back EMF effect. In fact, the spark consists of a
Rev. E | Page 12 of 20
ADM206E/ADM207E/ADM208E/ADM211E/ADM213E
burst of sparks as the relay contacts separate. The voltage
appearing on the line, therefore, consists of a burst of extremely
fast transient impulses. A similar effect occurs when switching
on fluorescent lights.
The fast transient burst test defined in IEC 1000-4-4 simulates
this arcing; its waveform is illustrated in Figure 29. It consists of
a burst of 2.5 kHz to 5 kHz transients repeating at 300 ms
intervals. It is specified for both power and data lines.

A simplified circuit diagram of the actual EFT generator is
illustrated in Figure 30.
The transients are coupled onto the signal lines using an EFT
coupling clamp. The clamp is 1 m long and surrounds the cable
completely, providing maximum coupling capacitance (50 pF to
200 pF typical) between the clamp and the cable. High energy
transients are capacitively coupled onto the signal lines. Fast rise
times (5 ns), as specified by the standard, result in very effective
coupling. Because high voltages are coupled onto the signal
lines, this test is very severe. The repetitive transients can often
cause problems where single pulses do not. Destructive latch-up
can be induced due to the high energy content of the transients.
Note that this stress is applied while the interface products are
powered up and are transmitting data. The EFT test applies
hundreds of pulses with higher energy than ESD. Worst-case
transient current on an I/O line can be as high as 40 A.
Test results are classified according to the following:
•
•
Classification 1: Normal performance within specification limits.
Classification 2: Temporary degradation or loss of
performance that is self recoverable.
IEC 1000-4-3 (previously IEC 801-3) describes the measurement method and defines the levels of immunity to radiated
electromagnetic fields. It was originally intended to simulate the
electromagnetic fields generated by portable radio transceivers
or any other devices that generate continuous wave-radiated
EM energy. Its scope has since been broadened to include
spurious EM energy that can be radiated from fluorescent
lights, thyristor drives, inductive loads, and other sources.
Testing for immunity involves irradiating the device with an EM
field. There are various methods of achieving this, including use of
anechoic chamber, stripline cell, TEM cell, and GTEM cell. A
stripline cell consists of two parallel plates with an electric field
developed between them. The device under test is placed within
the cell and exposed to the electric field. There are three severity
levels having field strengths ranging from 1 V/m to 10 V/m.
Results are classified in a similar fashion to those for IEC 1000­4­4.
•
•
•
•
Classification 1: Normal operation.
Classification 2: Temporary degradation or loss of function
that is self recoverable when the interfering signal is
removed.
Classification 3: Temporary degradation or loss of function
that requires operator intervention or system reset when
the interfering signal is removed.
Classification 4: Degradation or loss of function that is not
recoverable due to damage.
The ADM2xxE family of products easily meets Classification 1 at
the most stringent requirement (Level 3). In fact, field strengths
up to 30 V/m showed no performance degradation, and errorfree data transmission continued even during irradiation.

EMISSIONS/INTERFERENCE
SWITCHING GLITCHES
00068-032
EN 55022, CISPR 22 defines the permitted limits of radiated
and conducted interference from information technology (IT)
equipment. The objective of the standard is to minimize the
level of emissions, both conducted and radiated.
Figure 32. Switching Glitches
80
For ease of measurement and analysis, conducted emissions are
assumed to predominate below 30 MHz, and radiated emissions
are assumed to predominate above 30 MHz.
70
The ADM2xxE have been designed to minimize the switching
transients and ensure break-before-make switching, thereby
minimizing conducted emissions. This results in emission
levels well below specified limits. Other than the recommended 0.1 μF capacitor, no additional filtering/decoupling
is required.
Conducted emissions are measured by monitoring the line
power supply. The equipment used consists of a line impedance
stabilizing network (LISN) that essentially presents a fixed
impedance at RF and a spectrum analyzer. The spectrum
analyzer scans for emissions up to 30 MHz. A plot for the
ADM211E is shown in Figure 33.

This is a measure of noise that is conducted onto the line power
supply. Switching transients from the charge pump that are 20 V
in magnitude and that contain significant energy can lead to
conducted emissions. Another source of conducted emissions is
the overlap in switch-on times in the charge pump voltage
converter. In the voltage doubler shown in Figure 31, if S2 has
not fully turned off before S4 turns on, a transient current glitch
occurs between VCC and GND that results in conducted emissions. Therefore, it is important that the switches in the charge
pump guarantee break-before-make switching under all conditions so instantaneous short-circuit conditions do not occur.

RADIATED EMISSIONS
Radiated emissions are measured at frequencies in excess of
30 MHz. RS-232 outputs designed for operation at high baud
rates while driving cables can radiate high frequency EM
energy. The previously described causes of conducted emissions
can also cause radiated emissions. Fast RS-232 output transitions can radiate interference, especially when lightly loaded
and driving unshielded cables. Charge pump devices are also
prone to radiating noise due to the high frequency oscillator
and the high voltages being switched by the charge pump. The
move toward smaller capacitors in order to conserve board
space has resulted in higher frequency oscillators being employed in the charge pump design, resulting in higher levels of
conducted and radiated emissions.
The RS-232 outputs on the ADM2xxE products feature a controlled slew rate in order to minimize the level of radiated
emissions, yet they are fast enough to support data rates of up to
230 kbps.
