February 1988

MM54HCT157/MM74HCT157 Quad

2-Input Multiplexer

MM54HCT158/MM74HCT158

Quad 2-Input Multiplexer (Inverted Output)

General Description

These high speed QUAD 2-to-1 line data selector/multiplex-

ers utilize advanced silicon-gate CMOS technology. They

possess the high noise immunity and low power consump-

tion of standard CMOS integrated circuits, as well as the

ability to drive 10 LS-TTL loads.

The 54HCT/74HCT logic family is functionally as well as

pin-out compatible with the standard 54LS/74LS logic fami-

ly. All inputs are protected from damage due to static dis-

charge by internal diode clamps to V

and ground.

Features

These devices each consist of four 2-input digital multiplex-

ers with common select and OUTPUT ENABLE inputs. On

the MM54HCT157/MM74HCT157, when the OUTPUT EN-

ABLE input is at logical ‘‘0’’ the four outputs assume the

values as selected from the inputs. When the OUTPUT EN-

ABLE input is at a logical ‘‘1’’ the outputs assume logical

‘‘0’’. The MM54HCT158/MM74HCT158 operates in the

same manner, except that its outputs are inverted. Select

decoding is done internally resulting in a single select input

only. If enabled, the select input determines whether the A

or B inputs get routed to their corresponding Y outputs.

Typical propagation delay: 14 ns data to any output

Power supply range: 5V 10%

Low power supply quiescent current: 80 mA maximum

(74HCT Series)

Low input current: 1 mA maximum

Completely TTL compatible

High output drive current: 60 mA minimum
