Quad 2-Channel Multiplexer

The TC74AC157 is an advanced high speed CMOS QUAD

2-CHANNEL MULTIPLEXER fabricated with silicon gate and

double-layer metal wiring C²MOS technology.

It achieves the high speed operation similar to equivalent

Bipolar Schottky TTL while maintaining the CMOS low power

dissipation.

This device consist of four 2-input digital multiplexer with

common select and strobe inputs.

When the STROBE input is held “H” level, selection of data

is inhibited and all the outputs become “L” level.

The SELECT decoding determines whether the A or B inputs

get routed to their corresponding Y outputs.

All inputs are equipped with protection circuits against static

discharge or transient excess voltage.
