SN74HCS157-Q1

SCLS820A – AUGUST 2020 – REVISED DECEMBER 2021

SN74HCS157-Q1 Automotive Quadruple 2-to-1 Multiplexer with Schmitt-Trigger Inputs

1 Features

3 Description

•

AEC-Q100 qualified for automotive applications:

– Device temperature grade 1:

–40°C to +125°C, T_A

– Device HBM ESD Classification Level 2

– Device CDM ESD Classifcation Level C6

Available in wettable flank QFN (WBQB) package

Wide operating voltage range: 2 V to 6 V

Schmitt-trigger inputs allow for slow or noisy input

signals

The SN74HCS157-Q1 contains four data selectors/

multiplexers to select one of two data sources. All

channels are controlled by the same address select

(A/B) input, and strobe (G) input. A high level at the

strobe terminal forces all outputs low.
