# What does a 2 to 1 multiplexer circuit do?

## What does a 2 to 1 multiplexer circuit do?

A 2-to-1 multiplexer consists of two inputs D0 and D1, one select input S and one output Y. Depending on the select signal, the output is connected to either of the inputs. Since there are two input signals, only two ways are possible to connect the inputs to the outputs, so one select is needed to do these operations.

### How many basic logic gates are required for a 1 to 8 multiplexer?

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

How do you create a 2 1 multiplexer?

In 2×1 multiplexer, there are only two inputs, i.e., A0 and A1, 1 selection line, i.e., S0 and single outputs, i.e., Y. On the basis of the combination of inputs which are present at the selection line S0, one of these 2 inputs will be connected to the output.

What is the significance of quadruple 2 to 1 line multiplexer?

The SN74LVC257A quadruple 2-line to 1-line data selector/multiplexer is designed for 2.7-V to 3.6-V VCC operation. The device is designed to multiplex signals from 4-bit data sources to 4-output data lines in bus-organized systems.

## When would you use a multiplexer?

A Multiplexer is used to increase the efficiency of the communication system by allowing the transmission of data such as audio & video data from different channels via cables and single lines.

### What is strobe in multiplexer?

A multiplexer is a circuit with many inputs but only one output. Pin 9 (STROBE) is an input signal that disables or enables the multiplexer. …

What is E in multiplexer?

Individual data lines are selected by the application of the appropriate binary signal to control lines A and B. When Ā = 1 the output of the MUX is d0, and when ĀB = 1 the output is d1, etc. When the input enable is E = 1 the four AND gates are enabled.

Which of the following logic gate can be implemented by using 2 1 multiplexer?

Answer: Implementation of NAND, NOR, XOR and XNOR gates requires two 2:1 Mux. First multiplexer will act as NOT gate which will provide complemented input to the second multiplexer.

## What are 2-to-1 multiplexers?

As the name justifies, the 2 to 1 Multiplexer is the one where we have two inputs and only one output. Let’s find what are 2:1 MUX. ” The kind of Multiplexer or MUX that contains two inputs, one Selector and one Output is called 2-to-1 MUX or multiplexer.

### How to use 2-to1 mux as an AND gate?

” The AND Gate is the one that consist of two inputs and gives the input HIGH only when both the Inputs are HIGH.” Follow the simple steps to use 2-to 1 MUX as an AND Gate. Set the value of D0 as 1. Change the values of S and D0 according to table and record your observations.

What is a multiplexer?

A Multiplexer is in important circuit and we define the Multiplexer as: “A multiplexer is Logical Combinational Device that contain many inputs but it has the functionality to choose one of the required inputs to work on it and show the output to the user. The inputs may be digital or analogue “

How to design a 2-to-1 multiplexer in SolidWorks?

To Design a 2-to-1 Multiplexer, we need the following material: Grab the required Material from the Pick Library one after the other by Pressing a “P” button present at the screen. Hit and hold the Name of the chosen Logic Gates one by one and arrange them at the screen according to the given image:
