Multiplexers

A multiplexer has

• one input and one output

• one input and many output

• many input and one output

• many inputs and many outputs

A multiplexer can be used as

• Counter

• Shift register

• Combinational circuit

• 7-segment display

A multiplexer with 3-bit data select inputs is a

• 4:1 multiplexer

• 8:1multiplexer

• 16:1multiplexer

• 32:1multiplexer

A demultiplexer has

• One data input and two or more than two data outputs

• One data output and two or more than two data inputs

• One data output and a number of data input and a number of select inputs

• One data output and a number of select inputs

A 4 x 1 MUX is used to implement a 3-input Boolean function as shown in figure. The Boolean function F (A, B, C) implemented is

• F (A, B, C) = Σ (1, 2, 4, 6)

• F (A, B, C) = Σ (2, 4, 5, 6)

• F (A, B, C) = Σ (1, 2, 6)

• F (A, B, C) = Σ (1, 5, 6)

Two input multiplexer would have

• 1 select line

• 2 select lines

• 4 select lines

• 3 select lines

A multiplexer is also called as a

• Coder

• parallel adder

• Data selector

• NOR gate
