4x1 Multiplexer has four data inputs I3, I2, I1 & I0, two selection lines s1 & s0 and one output Y. The block diagram of 4x1 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.

Multiplexer Quadrupling The 74153 MUX has two separate 2-input/4-row MUXs on it. To create a single 16-row truth table, we can start by implementing parts of the table on different MUXs, and then combining the two separate outputs into one output.

Applications of Multiplexer Multiplexer allow the process of transmitting different type of data such as audio, video at the same time using a single transmission line. Telephone Network – In telephone network, multiple audio signals are integrated on a single line for transmission with the help of multiplexers.

The TTL/MSI SN54/74LS151 is a high speed 8-input Digital Multiplexer. It provides, in one package, the ability to select one bit of data from up to eight sources. The LS151 can be used as a universal function generator to generate any logic function of four variables.

4x1 Multiplexer has four data inputs D0, D1, D2 & D3, two selection lines S0 & S1 and one output Y. The block diagram of 4x1 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.

The truth table of a 4-to-1 multiplexer is shown below in which four input combinations 00, 10, 01 and 11 on the select lines respectively switches the inputs D0, D2, D1 and D3 to the output. That means when S0=0 and S1 =0, the output at Y is D0, similarly Y is D1 if the select inputs S0=0 and S1= 1 and so on.

Title:- 74153 A Dual 4 line to 1 line Multiplexer Theory :- The. multiplexer, shortened to “MUX” or “MPX”, is a combinational logic circuit designed to switch one of several input lines through to a single common output line by the application of a control signal.
