Function

This is the pin to the P-channel MOSFET source for Switch A. Bypass to ground

through a 1µF capacitor. 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 capacitor. INB is independent of INA.

This is the pin to the P-channel MOSFET drain connection. Bypass to ground through

a 0.1µF capacitor.

Ground connection

Active-high input Switches between FAST (Logic H) and SLOW (Logic L) Slew rate

This is the pin to the P-channel MOSFET drain connection. Bypass to ground through

a 0.1µF capacitor.
