Where to use 74LS157 Multiplexer

74LS157 is a 2-input (2:1) Multiplexer IC. It has four similar multiplexers inside it and hence it is called a Quad package 2-Input Multiplexer. A Multiplexer as we know takes in 2 or more inputs and provides one of them as the output based on the Select line status.

74HC157 Multiplexer Working

Similarly, this IC has two input pins (Input I0 and Input I1) and one output pin (Output Y) which forms a 2:1 Multiplexer. Likewise, there are 4 Multiplexers each of 2-inputs and 1-output corresponding to it, all these four Multiplexers are controlled through a single Line Select Pin (S) hence they cannot function independently. Hence if you are looking for a 2:1 Multiplexer IC with a quad package then this IC might be the right choice for you.
