The SN74HCS153-Q1 is a high speed silicon gate CMOS multiplexer well suited to multiplexing and data routing applications. It contains two 4:1 multiplexers.

The SN74HCS153-Q1 operates asynchronously, with each Y output being equal to the input selected by the address inputs (A, B). Both channels are controlled by the same address inputs.

The strobe (G) inputs force the respective Y outputs low, regardless of the state of other inputs.

All inputs include Schmitt-triggers allowing for slow input transitions and providing additional noise margin.
