Quad 2-Channel Multiplexer

The TC74HCT157A is a high speed CMOS 2-CHANNEL

It achieves the high speed operation similar to equivalent

LSTTL while maintaining the CMOS low power dissipation.

This device may be used as a level converter for interfacing

TTL or NMOS to High Speed CMOS. The inputs are compatible

with TTL, NMOS and CMOS output voltage levels.

When STROBE is held high, selection of data is inhibited

and all the outputs become low.

The SELECT decoding determines whether the A or B inputs

get transferred to their corresponding Y outputs.

All inputs are equipped with protection circuits against static

discharge or transient excess voltage.

Features

• Wide interfacing ability: LSTTL, NMOS, CMOS

• Output drive capability: 10 LSTTL loads

• Pin and function compatible with 74LS157

Pin Assignment

Note: xxxFN (JEDEC SOP) is not available in

Japan.
