How many input inputs are required for a 16 1 mux?

4 selection
16×1 Multiplexer We know that 8×1 Multiplexer has 8 data inputs, 3 selection lines and one output. Whereas, 16×1 Multiplexer has 16 data inputs, 4 selection lines and one output. So, we require two 8×1 Multiplexers in first stage in order to get the 16 data inputs.

How many 2×1 multiplexers are required to construct a 16×1 multiplexer?

Explanation: use 8 (2×1) mux that will give you 16 input and 8 output.

How many 4x MUX is required to implement a 16 1 mux?

So we need five 4:1 mux to make one 16:1 mux.

How can build a 16 1 mux using multiple 4 1 MUX and few logic gates?

The basis: See it this way: You need a combinational logic with 16 input pins, 4 select lines and one output. In a 4:1 mux, you have 4 input pins, two select lines and one output. So, at the least you have to use 4 4:1 MUX, to obtain 16 input lines. But you’d then have a logic with 4 output pins.

Which IC is used for the implementation of 1 to 16 demux?

IC 74154
Explanation: IC 74154 is used for the implementation of 1-to-16 DEMUX, whose output is inverted input.

How do you create a 16 1 multiplexer?

So, at the least you have to use 4 4:1 MUX, to obtain 16 input lines. But you’d then have a logic with 4 output pins. We can use another 4:1 MUX, to multiplex only one of those 4 outputs at a time. Hence, this would be your final design.

How do you implement mux?

Implementation of SOP function using multiplexer

1. Step 1: Draw the truth table for the given number of variable function.
2. Step 2: Consider one variable as input and remaining variables as select lines.
3. Step 3: Form a matrix where input lines of MUX are columns and input variable and its compliment are rows.

How do you make a 16 1 mux using 4 1 mux?

How do you make a 16 1 MUX using 4 1 mux?

What is a multiplexer IC 74151?

MULTIPLEXER IC 74151. Depending upon the digital code applied at the select inputs one out of n data input is selected & transmitted to a single o/p channel. Normally strobe (G) input is incorporated which is generally active low which enables the multiplexer when it is LOW. Strobe i/p helps in cascading.

How to get 16 input lines from a 4×1 MUX?

In a 4:1 mux, you have 4 input pins, two select lines and one output. So, at the least you have to use 4 4:1 MUX, to obtain 16 input lines. But you’d then have a logic with 4 output pins.

How many 2 to 1 multiplexers are there in one IC?

Generally four 2 line to 1 line multiplexers are fabricated in a single IC. Some of the popular ICs of 2 to 1 multiplexers include IC 74157 and IC 74158. Both these ICs are Quad 2-to-1 Multiplexers. While IC 74157 has a normal output, the IC74158 has an inverted output.

How many 4×1mux are used in 16×1 MUX?

\\$\\begingroup\\$ Q 16×1 mux by using 4×1mux Ans:. It contains four 4×1mux are used & it is a 16×1 mux 16 i/p are used the selective lines are S0, s1 ,s2, s3 , and 4 not gates are used and o/p are “y”.
