DESCRIPTION

The 74AC157 is an advanced high-speed CMOS

QUAD 2-CHANNEL MULTIPLEXER fabricated

with sub-micron silicon gate and double-layer

metal wiring C2MOS tecnology.

It consists of four 2-input digital multiplexer with

common SELECT and STROBE inputs. It is a

non-inverting multiplexer. When the STROBE

input is held high selection of data is inhibit and all

the outputs become low. 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.
