Pin Descriptions

Pin #

Symbol

Function

1

INA

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

2

ENA

Active-High Enable Input A. A logic low turns the switch off and the device consumes less than 1μA of cur-

rent. Logic high resumes normal operation.

3

ENB

Active-High Enable Input B. A logic low turns the switch off and the device consumes less than 1μA of cur-

rent. Logic high resumes normal operation.

4

INB

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.

5

OUTB

This is the pin to the P-channel MOSFET drain connection. Bypass to ground through a 0.1μF capacitor.

6

GND

Ground connection

7

FAST

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

8

OUTA

This is the pin to the P-channel MOSFET drain connection. Bypass to ground through a 0.1μF capacitor.
