DESCRIPTION

The M54/74HCT257 and the M54/74HCT258 are

high speed CMOS MULTIPLEXERs fabricated with

silicon gate C²MOS technology.

They have the same high speed performance of

LSTTL combined with true CMOS low power con-

sumption.

These IC’s are composed of an independent 2-

channelmultiplexer with commonSELECT and EN-

ABLE INPUT.

The M54/74HCT258 is an inverting multiplexer

while the M54/74HCT257 is a non-inverting multi-

plexer. When the ENABLE INPUT is held ”High”,

outputs of both IC’s become high-impedance state.

If SELECTINPUTis held”Low”, ”A” datais selected,

when SELECT INPUT is high ”H”, ”B” data is

chosen.

HCT258

All inputs are equipped with protection circuits

against static discharge and transient excess volt-

age.

This integrated circuit has input and output charac-

teristics that are fully compatible with 54/74 LSTTL

logic families. M54/74HCT devices are designed to

directly interface HSC²MOS systems with TTL and

NMOS components. They are also plug in replace-
