MM74HC157

Quad 2-Input Multiplexer

The 74HC logic family is functionally as well as pin-out

compatible with the standard 74LS logic family. All inputs

are protected from damage due to static discharge by inter-

nal diode clamps to V_CCand ground.

General Description

The MM74HC157 high speed Quad 2-to-1 Line data selec-

tor/Multiplexers utilizes advanced silicon-gate CMOS tech-

nology. It possesses the high noise immunity and low

power consumption of standard CMOS integrated circuits,

as well as the ability to drive 10 LS-TTL loads.

Features

■ Typical propagation delay: 14 ns data to any output

This device consists of four 2-input digital multiplexers with

common select and STROBE inputs. When the STROBE

input is at logical “0” the four outputs assume the values as

selected from the inputs. When the STROBE input is at a

logical “1” the outputs assume logical “0”.

■ Wide power supply range: 2–6V

■ Low power supply quiescent current: 80 µA maximum

(74HC Series)

■ Fan-out of 10 LS-TTL loads

■ Low input current: 1 µA maximum
