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

1 Features

3 Description

•

Wide operating voltage range: 2 V to 6 V

Schmitt-trigger inputs allow for slow or noisy input

signals

Low power consumption

– Typical I_CCof 100 nA

The SN74HCS157 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.

•

– Typical input leakage current of ±100 nA

±7.8-mA output drive at 6 V

Extended ambient temperature range: –40°C to

+125°C, T_A
