What is CD4051?

CD4051 is an 8 channel analog multiplexer & demultiplexer, controlled by digital signal. So, they are commonly referred as Digitally-controlled Analog Switches. It has low ON impedance and very low OFF leakage current. It dissipates a very low power over full VDD-VSS & VDD-VEE voltage ranges.

What is multiplex and demultiplexer?

Definition. Multiplexer refers to a type of combinational circuit that accepts multiple inputs of data but provides only a single output. The demultiplexer refers to the type of combinational circuit that accepts just a single input but directs it through multiple outputs. Technique of Conversion.

Can a multiplexer be used as a demultiplexer?

In particular, it includes internal logic that buffers one of the inputs as a TTL-level output on the output pin, and as a result, it cannot be used as a demultiplexer.

What are the types of multiplexer and demultiplexer?

The different types of multiplexers are 8-1 MUX, 16-1 MUX, and 32-1 MUX. The different types of demultiplexers are 1-8 Demux, 1-16 Demux, 1-32 Demux. In demultiplexer, the selection of output line can be controlled through n-selection lines bit values.

What is meant by demultiplexer?

Definition of demultiplexer : an electronic device that separates a multiplex signal into its component parts.

What is a multiplex system?

The multiplex wiring system allows multiple electronic messages to travel back and forth through the same datalink wire, just as broadband cable allows telephone, television and Internet connections to travel through the same line.

Is decoder same as demultiplexer?

A Decoder decodes an encrypted input signal to multiple output signals from one format to another format. A De-Multiplexer routes an input signal to multiple output signals. A Decoder has ‘n’ input lines and maximum of 2n output lines. A De-Multiplexer has single input, ‘n’ selection lines and maximum of 2n outputs.

Where is demultiplexer used?

Demultiplexer (Demux) and Multiplexer (MUX) both are used in communication systems to carry multiple data signals (i.e. audio, video etc) using single line for transmission. In this easier process, Demultiplexer receive the output data of Multiplexer (as a receiver) and covert back them to the original form then.
