CS4853 Multiplexer Demultiplexer IC

A multiplexer is a circuit that receives several inputs but only outputs one. A demultiplexer works in the opposite direction of a multiplexer, accepting just one input and producing several outputs. In many communication systems, multiplexer and demultiplexer are used together. The term “multiplexer” refers to a device that combines several functions into one. A multiplexer is a circuit that allows you to choose and route any of several input signals to a single output. A single-pole multi-position switch is a simple example of a multiplexer’s non-electronic circuit.

Multi-position switches are included in a wide range of electrical circuits. Circuits that operate at high speeds, on the other hand, require the multiplexer to be picked automatically. This duty is too difficult for a mechanical switch to handle. As a result, a multiplexer is utilised to carry out high-speed switching using electronic components. Multiplexers can deal with both analogue and digital data. Multiplexer made of relays and transistor switches for analogue applications. They made digital applications out of ordinary logic gates.

A digital multiplexer, sometimes known as a digital multiplexer, is a circuit having several inputs but only one output. We can direct any input to the output by using control signals (also known as Select Signals). 2-to-1, 4-to-1, 8-to-1, and 16-to-1 multiplexers are some of the most prevalent types of multiplexers.

The term “demultiplexer” refers to a device that converts one signal into multiple signals. A demultiplexer is a circuit that has one input and multiple outputs. We can direct any input to the output by using a control signal. 1-to-2, 1-to-4, 1-to-8, and 1-to-16 demultiplexers are a few examples of demultiplexers.
