Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the
device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If
these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be
affected.

2. Measured by the voltage drop between A and B pins at the indicated current through the switch. On
Resistance is determined by the lower of the voltages on the two (A or B Ports).
3. Parameter is characterized but not tested in production.
4. DRON = RON max − RON min measured at identical Vcc, temperature and voltage levels.
5. Flatness is defined as the difference between the maximum and minimum value of On Resistance over the
specified range of conditions.

6. This parameter is guaranteed by design but not tested. The bus switch contributes no propagation delay
other than the RC delay of the On Resistance of the switch and the 50pF load capacitance, when driven by an
ideal voltage source (zero output impedance).
