Multiplexer Circuits

• A Multiplexer is a circuit that accepts many inputs but gives only one output.

• Multiplexer circuit means many into one.

• A multiplexer circuit is used to select and route any one of the several input signals to a single output.

Significance of Multiplexer Circuits:

• It can facilitate the transmission of data through a single line.

• It uses fewer wires.

• It reduces the cost and the complexity of the system.

• It doesn’t require K-maps & any simplification.

• It can make the transmission circuit less complex and economical.

• It can improve the reliability of the digital system and reduce the number of exterior wired connections.

• Its ability can be extended to switch audio signals, video signals, etc.

• The implementation of a number of combination circuits can be possible.

• The logic designs can be simplified.

• The dissipation of heat is less because of the analog switching current which ranges from 10mA to 20mA.

Based on its significance multiplexer circuits used in various applications as follows:

• Communication System

• Computer Memory

• Telephone Network

• Transmission from the Computer System of a Satellite

De-multiplexer Circuits

• A De-multiplexer is a circuit that accepts only one input and gives many outputs.

• De-multiplexer circuit means one to many.

• In A de-multiplexer circuit apply a control signal, to steer any input to the output.

Significance of De-multiplexer Circuits:

• It takes a single high-speed source signal and spreads it across multiple low-speed circuits.

• It connects a single source to multiple destinations.

• It divides the mutual signals back into separate streams.

• It enables several rows in memory chips based on the address.

• De-multiplexer circuits are used within CLK data recovery solutions.

• It is used as a decoder within the security systems of banking sectors.

• It is used for the reconstruction of parallel data and ALU circuits.

• It is used in the broadcasting of ATM packets

• It is also used in synchronous systems for data transmission, data acquisition systems.

• The efficiency of the communication system can be enhanced through the combination of Mux & Demux.

• The Audio or Video signals transmission also needs a combination of Mux and Demux.

• The implementation of a number of combination circuits can be possible.

Based on its significance de-multiplexer circuits used in various applications as follows:

• Control Systems

• Communication System

• Wavelength Routers.

• Arithmetic Logic Unit (ALU)

• Serial to Parallel Converter
