1, 16, 9, 8

IN1–IN4

Logic-Control Digital Inputs

2, 15, 10, 7

COM1–COM4

Analog Switch Common* Terminals

PIN

3, 14, 11, 6

NC1–NC4

Analog Switch Normally Closed Terminals

4

V-

Negative Analog Supply-Voltage Input. Connect to GND for single-

supply operation.

13

V+

Positive Analog and Digital Supply Voltage Input. Internally con-

nected to substrate.

12

N.C.

No Connect. Not internally connected.

5

GND

Ground. Connect to digital ground. (Analog signals have no ground

reference; they are limited to V+ and V-.)

*NO_ (or NC_) and COM_ pins are identical and interchangeable. Either may be considered as an input or output; signals pass

equally well in either direction.
