How do you make a 1/8 demultiplexer?

A 1 to 8 demultiplexer consists of one input line, 8 output lines and 3 select lines. Let the input be D, S1 and S2 are two select lines and eight outputs from Y0 to Y7. It is also called as 3 to 8 demux because of the 3 selection lines.

How many and gates are required for a 1-to-16 demultiplexer?

Explanation: The number of AND gates required will be equal to the number of outputs in a demultiplexer, which are 8. Explanation: The output Y4 = Q2.(Q1)’.(Q0)’.I. since the bit combinations of 4 are 100. 11. Which IC is used for the implementation of 1-to-16 DEMUX?

Which IC used for implementation of 1/16 Demux?

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

How many select lines would be required for an 1 line to 16 line demultiplexer?

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 do demultiplexers work?

The demultiplexer takes one single input data line and then switches it to any one of a number of individual output lines one at a time. The demultiplexer converts a serial data signal at the input to a parallel data at its output lines as shown below.

How can an decoder can be used as demultiplexer?

A decoder with an enable input can function as a Demultiplexer. A demultiplexer is a circuit that receives information on a single line and transmits this information on one of 2n possible output lines. Selection of a specific output line is controlled by the bit values of n selection lines.

What is the IC number of 1 to 16 demux?

74154
These are available in different IC packages and some of the most commonly used demultiplexer ICs includes 74139 (dual 1:4 DEMUX), 74138 (1:8 DEMUX), 74237 (1:8 DEMUX with Address Latches), 74154 (1:16 DEMUX), 74159 (1:16 DEMUX open collector type), etc.

How many select lines would be required for an 1 line to 8 line demultiplexer?

How many select lines would be required for an 8- line-to-1-line multiplexer? Explanation: 2n input lines, n control lines and 1 output line available for mux. here, 8 input lines mean 23 inputs. so, 3 control lines are possible.
