DESCRIPTION(2)

NAME

NO.

S2B

I/O

Source pin 2B. Can be an input or output.

S2A

I/O

Source pin 2A. Can be an input or output.

S3B

I/O

Source pin 3B. Can be an input or output.

I/O

Drain pin 3. Can be an input or output.

S3A

I/O

Source pin 3A. Can be an input or output.

Active low logic enable. When this pin is high, all switches are turned off. When this pin is low, the SELx

inputs determine switch connection as listed in Table 8-1.

VSS

Negative power supply. This pin is the most negative power-supply potential. For reliable operation,

connect a decoupling capacitor ranging from 0.1µF to 10µF between VSS and GND. VSS must be

connected to ground for single supply voltage applications.

GND

Ground (0V) reference

SEL3

Logic control select pin 3. Controls switch 3 connection as listed in Table 8-1.

SEL2

Logic control select pin 2. Controls switch 2connection as listed in Table 8-1.

SEL1

Logic control select pin 1. Controls switch 1 connection as listed in Table 8-1.

S1A

I/O

Source pin 1A. Can be an input or output.

S1B

I/O

Source pin 1B. Can be an input or output.

I/O

Drain pin 1. Can be an input or output.

I/O

Drain pin 2. Can be an input or output.

VDD

Positive power supply. This pin is the most positive power-supply potential. For reliable operation,

connect a decoupling capacitor ranging from 0.1µF to 10µF between VDD and GND.
