TYPE(1)

DESCRIPTION(2)

NAME

NO.

SEL1

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

S1A

I/O

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

I/O

Drain pin 1. Can be an input or output.

S1B

I/O

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

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.

S2B

I/O

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

I/O

Drain pin 2. Can be an input or output.

S2A

I/O

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

SEL2

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

SEL3

Logic control select pin 3. Controls switch 3 connection as listed in Table 8-2.

S3A

I/O

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

I/O

Drain pin 3. Can be an input or output.

S3B

I/O

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

N.C.

Not Connected

Not Connected. Can be shorted to GND or left floating.

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.

S4B

I/O

Source pin 4B. Can be an input or output.

I/O

Drain pin 4. Can be an input or output.

S4A

I/O

Source pin 4A. Can be an input or output.

SEL4

Logic control select pin 4. Controls switch 4 connection as listed in Table 8-2.

(1)

I = input, O = output, I/O = input and output, P = power
