Feature 74HC157; 74HCT157 Quad 2-input multiplex er Rev.
8 — 28 December 2015 Product data sheet 1.
General description The 74HC157; 74HCT157 is a high-speed Si-g ate CMOS device and is pin compatible w ith Low-power Schottky TTL.
It is speci fied in compliance with JEDEC standard no.
7A.
The 74HC/HCT157 are quad 2-inpu t multiplexers which select 4 bits of d ata from two sources under the control of a common data select input (S).
The enable input (E) is active LOW.
When E is HIGH, all of the outputs (1Y to 4Y) are forced LOW regardless of all other input conditions.
Moving the data from two groups of re .

Description Quad 2-input multiplexer
Feature 74HC157; 74HCT157 Quad 2-input multiplex er Rev.
9 — 24 July 2020 Product dat a sheet 1.
General description The 74H C157; 74HCT157 is a quad 2-input multip lexer.
The device features select (S) a nd enable E inputs.
A HIGH on S selects data source 1, a LOW data source 0.
A HIGH on E forces all the outputs (1Y to 4Y) LOW.
Inputs include clamp diodes.
This enables the use of current limitin g resistors to interface inputs to volt ages in excess of VCC.
