2 Applications
• Data selection
• Multiplexing

3 Description
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.
