# How many and gates are required for 1 to 8 demultiplexer?

## How many and gates are required for 1 to 8 demultiplexer?

8 AND gates
For a 1 to 8 multiplexer a total of 8 AND gates are required.

### How many lines does a 1/8 demultiplexer have?

3 select lines
A 1 to 8 demultiplexer consists of one input line, 8 output lines and 3 select lines. Let the input be D, S1 and S2 are two select lines and eight outputs from Y0 to Y7.

Which IC is required to implement a 1 to 8 demultiplexer?

Another commonly used 1-to-8 demultiplexer integrated circuits is the IC 74138. The pinout is very similar except that there is no Latch Enable input (as all the enable pins are normal enable pins – two are active LOW and one is active HIGH) and the outputs are active LOW.

What is demux explain with diagram?

The block diagram of 1×16 De-Multiplexer using lower order Multiplexers is shown in the following figure. The common selection lines s2, s1 & s0 are applied to both 1×8 De-Multiplexers. The outputs of upper 1×8 De-Multiplexer are Y15 to Y8 and the outputs of lower 1×8 DeMultiplexer are Y7 to Y0.

## How many select lines are required for a 1 to 8 the multiplexer?

3
Example: An 8 × 1 multiplexer selects one of the 8 inputs and presents it to the output, i.e. So the number of select lines will be 3.

### What is demultiplexer in digital logic design?

The demultiplexer is a combinational logic circuit designed to switch one common input line to one of several seperate output line. The data distributor, known more commonly as a Demultiplexer or “Demux” for short, is the exact opposite of the Multiplexer we saw in the previous tutorial.

What is demux application?

Demultiplexer is used to connect a single source to multiple destinations. The main application area of demultiplexer is communication system, where multiplexers are used. Most of the communication system are bidirectional i.e., they function in both ways (transmitting and receiving signals).

What are the applications of demultiplexer Demux?

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.

## What is demux and its application?

### What is MUX computer architecture?

A Multiplexer (MUX) can be described as a combinational circuit that receives binary information from one of the 2^n input data lines and directs it to a single output line. The selection of a particular input data line for the output is decided on the basis of selection lines.

How do you make a MUX?

To construct a 4:1 MUX using a 2:1 MUX, we will have to combine three 2:1 MUX together. The end result should give us 4 Input pins, 2 Control/Select Pins and one output pin. To achieve the first two MUX is connected in parallel and then the output of those two are feeded as input to the 3rd MUX as shown below.
