Description
This device consists of four independent precisionvoltage comparators. All these
comparators weredesigned specifically to operate from a singlepower supply over a
wide range of voltages.Operation from split power supplies is alsopossible.
These
comparators

1. At output switch point, VO ≈ 1.4V, RS = 0 with VCC
from 5V to 30V, and over the
full input common-mode
range (0V to VCC
–1.5V).2.The direction of the input current is out of the IC due
to the PNP input stage. This current is essentially
constant, independent of the state of the output, so no loading charge exists on the
reference of input lines3.The input common-mode voltage of either input signal
voltage should not be allowed to go negative by more
than 0.3V. The upper end of the common-mode voltage range is VCC
or both inputs can go to
–1.5V, but either
30V without damage.4.The response time specified is for
a 100mV input step with 5mV overdrive.

voltage
may

supply
lhttp://doc.xuehai.net/b9bcc8a4eaeecbb1161a2b152.htmlevel. As long as the other
voltage remains
within the common-mode range, the comparator will provide a proper output state. The
low input voltage state must not be less than –0.3V (or 0.3V bellow the negative
power supply, if used)6.Maximum values are guaranteed by design.
