Demultiplexer


A demultiplexer , sometimes abbreviated dmux, is a circuit that has one input and more than one output. It is used when a circuit wishes to send a signal to one of many devices. This description sounds similar to the description given for a decoder, but a decoder is used to select among many devices while a demultiplexer is . As inverse to the MUX , demux is a one-to-many circuit. With the use of a demultiplexer , the binary data can be bypassed to one of its many output data lines.

An electronic multiplexer can be considered as a multiple-input, single-output switch, and a demultiplexer as a single-input, multiple-output switch. Demultiplexers are mainly used in Boolean function generators and . It is quite opposite to multiplexer or MUX. It is a process of taking information from one input and transmitting over one of many outputs. DEMUX are used to implement general-purpose logic systems. Mux accepts many inputs and gives only one output.

Demux accepts one input but gives many outputs. De-multiplexer takes one single input data line, and then switches it to any one of the output line. AND gates for achieving the operation.

Dolayısıyla n= adet seçme ucu olacaktır. Read about the multiplexer first. When the output enable (E) is. Low, the device passes data at input A to outputs Y(true) and Y1.

As a demultiplexer , data at input E is routed to either. Yor Ydepending on the state of A. The other data outputs . Multiplex “çoktan bire”, demultiplex ise “birden çoğa” anlamına gelir. It can often refer as data distributor or demux. It can perform as single input many output switch. In a MUX you have one of n inputs to choose from and direct to an output.

In a DeMUX, you have a single input, . Answer to Why is a demultiplexer sometimes called a data distributor? I find it useful to think of a demultiplexer as analogous to a railroad switch, controlled by the select input. This schematic shows a simple way of multiplexing two sources and then demultiplexing the signals to two outputs.

Diese Umschaltung kann . IDT offers a family of 3. These are ideal for bidirectional interfaces between mixed-supply buses, and in applications that require isolation and protection. A multiplexer is a circuit that accept many input but give only one output. Generally multiplexer and demultiplexer are used together, because of the communication systems are bi directional.

To design and simulate decoders, encoders, multiplexer and demultiplexer. LE), and an active LOW enable input (E). Qto Q15) are mutually exclusive active HIGH.

Each decoder has an active-LOW Enable input which can be used as a data input for a 4-output demultiplexer. With two, three, or four addressing lines, this circuit can decode a two, three, or four-bit binary number, or can demultiplex up to four, eight, or sixteen time-multiplexed signals.
