NAME

NO.

S1

1

I/O

Source pin 1. Can be an input or output.

S2

2

I/O

Source pin 2. Can be an input or output.

N.C.

3

—

No internal connection. Can be shorted to GND or left floating.

GND

4

P

Ground (0 V) reference

VDD

5

P

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

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

SEL1

6

I

Logic control input, has internal pull-down resistor. Controls the switch connection as shown in Section 8.5.

SEL2

7

I

Logic control input, has internal pull-down resistor. Controls the switch connection as shown in Section 8.5.

VSS

8

P

Negative power supply. This pin is the most negative power-supply potential. In single-supply applications, this pin

can be connected to ground. For reliable operation, connect a decoupling capacitor ranging from 0.1 µF to 10 µF

between VSS and GND.

D2

9

I/O

Drain pin 1. Can be an input or output.

D1

10

I/O

Drain pin 2. Can be an input or output.

(1)

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