# How many enable line are available in 4 1 mux?

## How many enable line are available in 4 1 mux?

A 4-to-1 multiplexer consists four data input lines as D0 to D3, two select lines as S0 and S1 and a single output line Y.

What is enable in multiplexer?

An enable input makes the multiplexer operate. When EN = 0, the output is High-Z or less commonly LOW (depending on the specific device). When EN = 1, the multiplexer performs its operation depending on the selection line.

### Does multiplexer have enable line?

multiplexers usually have an ENABLE input that can be used to control the multiplexing function. When this input is enabled, that is, when it is in logic ‘1’ or logic ‘0’ state, depending upon whether the ENABLE input is active HIGH or active LOW respectively, the output is enabled. The multiplexer functions normally.

What will be the output of 4 1 mux if the value in selection lines S0 1 and S1 1?

4×1 Multiplexer: In the 4×1 multiplexer, there is a total of four inputs, i.e., A0, A1, A2, and A3, 2 selection lines, i.e., S0 and S1 and single output, i.e., Y. On the basis of the combination of inputs that are present at the selection lines S0 and S1, one of these 4 inputs are connected to the output.

#### What is the function of an enable input on a multiplexer chip?

What is the function of an enable input on a multiplexer chip? Explanation: Enable input is used to active the chip, when enable is high the chip works (ACTIVE), when enable is low the chip does not work (MEMORY).

What is the function of enable input on a multiplexer chip?

## What is function of Enable pin in multiplexer?

Multiplexer circuits typically have an enable input (EN pin in Fig. 1) in addition to the other inputs. The EN pin functions as a global on/off switch. As an example of how a multiplexer’s EN pin operates, a truth table is shown below in Fig.

What is the use of Enable pin?

The enable pin of ON Semiconductor eFuses provides a number of features. With all eFuses, a transistor may be used to force the pin low to disable the output. In addition, it may be left floating if no control of the enable pin is required.

### Why Enable is used?

An Enable will allow an input signal, shown in green, to pass the output, shown in red, when the control signal is high. It will prevent a signal from passing when the control signal is switched to low.

What is an enable circuit?

#### What is role of Enable?

When you enable a role in a session, you obtain all privileges assigned to that role. You can enable multiple roles simultaneously, thereby gaining all privileges of those roles, plus any privileges that are already granted to you directly. By default, only predefined roles are enabled automatically for users.

What are enable pins?

## What is 4 to 1 multiplexer?

One of these data inputs will be connected to the output with the select lines. Since there are ‘n’ selection lines, there will be about 2 n combinations of “1” and “0”. 4 to 1 Multiplexer is also known as 4 to 1 MUX circuit. In this tutorial, we are going to steady about behavior of 4 to 1 multiplexer.

How to design 4 to 1 multiplexer using logic gates?

Here are the steps to design or construct 4 to 1 Multiplexer or 4:1 MUX using Logic Gates : 1 Now, make a diagram of multiplexer with 4 input lines, 2 selection lines and 1 output. 2 This is how a truth table for 4 to 1 MUX looks like . 3 In last step, design 4 to 1 multiplexer by using 4 AND gates and a single OR gate.

### How many selection lines are there in 4 to 1 multiplexer?

Since there are ‘n’ selection lines, there will be about 2 n combinations of “1” and “0”. 4 to 1 Multiplexer is also known as 4 to 1 MUX circuit. In this tutorial, we are going to steady about behavior of 4 to 1 multiplexer.

What is the output of the multiplexer?

According to the truth table, the output of the multiplexer fully depends on selection lines (binary data , 00,01,10 & 11) and one input would be selected from all the input data lines as the output. When S 0 =0 and S 1 =0 , then A 0 would be the output. Similarly When S 0 =0 and S 1 =1 , then A 1 would be the output.
