Function
Active-high input switches between FAST (Logic H) and SLOW (Logic L) slew rate.
This is the pin to the P-channel MOSFET source for Switch A. Bypass to ground through a 1μF capaci-
tor. INA is independent of INB.
Active-High Enable Input A. A logic low turns the switch off and the device consumes less than 1μA of
current. Logic high resumes normal operation.
Active-High Enable Input B. A logic low turns the switch off and the device consumes less than 1μA of
current. Logic high resumes normal operation.
This is the pin to the P-channel MOSFET source for Switch B. Bypass to ground through a 1μF capaci-
tor. INB is independent of INA.
Not connected.
This is the pin to the P-channel MOSFET drain connection. Bypass to ground through a 0.1μF capacitor.
Ground connection.
