How many and gates do we need for a 4×1 mux?
The below figure shows the logic circuit of 4:1 MUX which is implemented by four 3-inputs AND gates, two 1-input NOT gates, and one 4-inputs OR gate. In this circuit, each data input line is connected as input to an AND gate and two select lines are connected as other two inputs to it.
How do you create a 4×1 multiplexer using logic gates?
A multiplexer is a Combinational circuit (it is a type of circuit whose output rely on the given inputs using various logic gates ) that takes multiple inputs and delivers only a single output. It consists input data lines, selection lines and a single output….Truth table.
| Selection Lines | Output | |
|---|---|---|
| 0 | 1 | A1 |
| 1 | 0 | A2 |
| 1 | 1 | A3 |
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.
Which IC is used for the implementation of dual 4 1 MUX?
IC Used
| IC Number | IC Name |
|---|---|
| 74LS153 | Dual 4-Line to 1-Line Data Selectors/Multiplexers |
Which of the following is correct for a multiplexer?
Which of the following is correct for multiplexer? Explanation: Multiplexer has several inputs and a single output line and it is used for data selection. Explanation: Multiplexers work with both analog and digital signals. Explanation: TDM or Time division multiplexing is a type of multiplexing.
How many gates are in a MUX?
Multiplexer Input Line Selection Then the implementation of the Boolean expression above using individual logic gates would require the use of seven individual gates consisting of AND, OR and NOT gates as shown.
What is MUX gate?
In electronics, a multiplexer (or mux; spelled sometimes as multiplexor), also known as a data selector, is a device that selects between several analog or digital input signals and forwards the selected input to a single output line. The selection is directed by a separate set of digital inputs known as select lines.
