74HC157; 74HCT157 Quad 2-input multiplexer Rev.
9 — 24 July 2020 Product data sheet 1.
General description The 74HC157; 74HCT157 is a quad 2-input multiplexer.
The device features select (S) and 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 limiting resistors to interface inputs to voltages in excess of VCC.
