How many and gates do we need for a 4×1 mux?
From the above expression of the output, a 4-to-1 multiplexer can be implemented by using basic logic gates. 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.
How many and gates are required for a 1 to 1 multiplexer?
For a 1 to 8 multiplexer a total of 8 AND gates are required.
Which IC is used for 4×1 multiplexer circuit?
Multiplexer Integrated Circuits (ICs)
| IC number | Function | Output State |

| 74151 | 8:1 multiplexer | Inverted output |
| 74153 | Dual 4-to-1 multiplexer | Output is equal to input |
| 74352 | Dual 4-to-1 multiplexer | Inverted output |
| 74157 | Quad 2-to-1 multiplexer | Output is equal to input |
How many gates are used in multiplexer?
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.
How many NAND gates are there in mux?
Thus, we require four 3-input NAND gates and a 4-input NAND gate to implement a 4×1 mux.
How many AND gates are required for OR gate?
Logic gate circuit it given below, Here, three NAND gates are used to make an OR gate.
What is a 4×1 MUX?
4×1 Multiplexer has four data inputs I3, I2, I1 & I0, two selection lines s1 & s0 and one output Y. The block diagram of 4×1 Multiplexer is shown in the following figure. One of these 4 inputs will be connected to the output based on the combination of inputs present at these two selection lines.
How many NOT gates are required for the construction of a 16 to 1 multiplexer?
A 16 × 1 multiplexer has 16 inputs so if we use 4 × 1 multiplexers: At first stage: 4 multiplexers are needed for 16 inputs, At second stage: the output of these 4 multiplexers is connected to inputs of 1 multiplexer. Total 4 × 1 multiplexers needed are 4 + 1 = 5.
Is MUX a universal gate?
NAND and NOR gates are basically known as universal gates, since you can implement any logic function with these. A multiplexer, in a sense, can also be termed as a universal gate, since, you can realize any function by using a mux as a look-up-table structure.
