# How many selection lines are required to design a 16 to 1 line mux?

## How many selection lines are required to design a 16 to 1 line mux?

Ans. For 16 to 1 MUX four select lines will be needed to select 16 (24) inputs.

How many not gates are required for the construction of a 16 to 1 multiplexer?

First multiplexer will act as NOT gate which will provide complemented input to the second multiplexer. Three(3) ​2 : 1 MUX are required to implement 4 : 1 MUX. Similarly, While 8 : 1 MUX require seven(7) ​2 : 1 MUX, 16 : 1 MUX require fifteen(15) ​2 :1 MUX, 64 : 1 MUX requires sixty three(63)​ 2 : 1 MUX.

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

74×150
List of ICs which provide multiplexing

IC No. Function Output State
74×352 Dual 4:1 mux. Output is inverted input
74x151A 8:1 mux. Both outputs available (i.e., complementary outputs)
74×151 8:1 mux. Output is inverted input
74×150 16:1 mux. Output is inverted input

How do you create a multiplexer?

2-input Multiplexer Design

1. Q = A.I0.I1 + A.I0.I1 + A.I0.I1 + A.I0.I1
2. Q = A.I1 + A.I0
3. The Boolean expression for this 4-to-1 Multiplexer above with inputs A to D and data select lines a, b is given as:
4. Q = abA + abB + abC + abD.

#### How many select lines will a 16 input multiplexer have?

So the number of select lines will be 4.

How many 4 * 1 mux are required to implement a 16 * 1mux?

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.

## How many select lines does a 4 1 multiplexer require?

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.

How many select lines will a 32 1 multiplexer have?

Ans. 5 select lines will be required for 32 inputs, as 25 = 32.

### How to create a 4 to 1 multiplexer in logic?

It consists input data lines, selection lines and a single output. To construct a 4 to 1 multiplexer, we need to know how many selection lines we required to create a MUX? We require n selection lines, where 2 n represents total input lines and n represents selection lines. (In this case, 2 2 that gives 4 input lines and 2 selection lines).

How to construct a 16 to 1 multiplexer?

About Us Construct 16-to-1 line multiplexer with two 8-to-1 line multiplexers and one 2-to-1 line multiplexer. Makes suitable assumptions, if any 5m Dec2005

#### How many input lines in a 4 mux logic?

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 input lines do you need for a multiplexer?

Depending on the number of input lines, one or more select lines may be required. For 2 n input lines, n select lines are needed. In hardware terms, this is basically the simplest of switches. To start out easy, we’ll create a multiplexer taking two inputs and a single selector line.
