Mnemonic

Description

1 to 12, 45 to 48

S16 to S1

Source Terminal. This pin may be an input or output.

13, 14

VDD

Most Positive Power Supply Potential.

15 to 19

A0 to A4

Logic Control Inputs.

20

CS

Chip Select Pin. CS is active low.

21

WR

Write Pin. When WR is low, the logic control inputs (A0 to A4) control which state the switches are in. On

the rising edge of WR, the logic control input data is latched.

22

EN

Active Low, Digital Input. When this pin is high, the device is disabled and all switches are off. When this

pin is low, the Ax logic control inputs determine the on switches. The EN input signal is not latched by WR.

23

GND

Ground (0 V) Reference.

24

VSS

Most Negative Power Supply in a Dual-Supply Application. In single-supply applications, connect this pin

to GND.

25 to 40

S17 to S32

Source Terminal. This pin may be an input or output.

41, 42, 44

NIC

Not Internally Connected. Do not connect to this pin.

43

D

Drain Terminal. This pin may be an input or output.

EPAD

Exposed Pad. The exposed pad must be connected to GND.
