Multiplexer: What is Multiplexer A Multiplexer

What is Multiplexer A Multiplexer , also known as a MUX, is a special type of combinational circuit used in digital electronics. The block diagram of an n-to-1 multiplexer and its equivalent circuit is shown in the figure below As shown in the figure, there are n-data inputs, one output, and a m select inputs, with 2 m = n A multiplexer makes it possible for several input signals to share one device or resource , for example, one analog-to-digital converter or one communications transmission medium, instead of having one device per input signal. Learn how multiplexers work, their truth tables, types, and applications in data routing, communication systems, and digital logic design.
