TC74HC157AP/AF/AFN Quad 2-Channel Multiplexer

TC74HC158AP/AF/AFN Quad 2-Channel

Multiplexer (inverting)

The TC74HC157A and TC74HC158A are high speed CMOS

2-CHANNEL MULTIPLEXERs fabricated with silicon gate

They achieve the high speed operation similar to equivalent

LSTTL while maintaining the CMOS low power dissipation.

The TC74HC158A is an inverting multiplexer while the

TC74HC157A is a non-inverting.

When STROBE is held high, selection of data is inhibited and

all the outputs become low in the case of HC157A or high in the

case of HC158A.

The SELECT decoding determines whether the A or B inputs

get transferred to their corresponding Y (

Y) outputs.

All inputs are equipped with protection circuits against static

discharge or transient excess voltage.

Features

• Output drive capability: 10 LSTTL loads

• Pin and function compatible with 74LS157/158

Note: xxxFN (JEDEC SOP) is not available in

Japan.
