DESCRIPTION

The AC158 is an high-speed CMOS QUAD

2-CHANNEL

MULTIPLEXER

(INVERTING)

fabricated with sub-micron silicon gate and

double-layer metal wiring C

ideal for low power applications maintaining high

speed operation similar to equivalent Bipolar

Schottky TTL.

It consists of four 2-input digital multiplexers with

common select and strobe inputs. It is an

inverting multiplexer. When the STROBE input is

held high selection of data is inhibit and all the

outputs become high. The

SELECT decoding

determines whether the A or B inputs get routed

to their corresponding Y outputs.

All

inputs and

outputs

are

equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
