Therefore, the expression for output Y0 is From the above table, the output Y0 is active when the combination of select line and input line are active low and high respectively, i.e., S D = 0 1В . We can derive the Boolean Expressions for the outputs as follows:ДЄssume S is the Select Input, D is the Data Input and Y0 and Y1 are the outputs of the 1-to-2 Demultiplexer. The truth table of a 1-to-2 demultiplexer is shown below, in which the input is routed to Y0 and Y1 depending on the value of select input S.

When the select input is LOW, then the input will be passed to Y0 and if the select input is HIGH, then the input will be passed to Y1. In the figure, there are only two possible ways to connect the input to output lines, thus only one select signal is enough to do the demultiplexing operation. The figure below shows the block diagram of a 1-to-2 demultiplexer with additional enable input. The signal on the select line helps to switch the input to one of the two outputs. 1-to-2 DemultiplexerДЄ 1-to-2 demultiplexer consists of one input line, two output lines and one select line. For example, 74159 is a 4-line to 16-line Decoder IC. NOTE: The Demultiplexer ICs are also called as Decoder ICs. 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. There are several types of demultiplexers based on the output configurations such as 1:2, 1:4, 1:8 and 1:16. For example, a 1-to-4 demultiplexer requires 2 (2 2 = 4) select lines to control the 4 output lines. In this, m select lines are required to produce 2 m possible output lines (consider 2 m = n). It consists of 1 input line, вЂnвЂ™ output lines and вЂmвЂ™ select lines. The figure below shows the block diagram of a demultiplexer or simply a DEMUX. Thus, a demultiplexer is a 1-to-N device, where as the multiplexer is an N-to-1 device. If Multiplexers are called as Data Selectors, then Demultiplexers are called as Data Distributors, since they transmit the same data which is received at the input to different destinations. The below figure illustrates the basic idea of demultiplexer, in which the switching of the input to any one of the four outputs is possible at a given instant. In order to select a particular output, we have to use a set of Select Lines and the bit combinations of these select lines control the selection of specific output line to be connected to the input at a given instant.

Demultiplexing is just the opposite of that.ДЄ Demultiplexer is a combinational logic circuit that receives the information on a single input line and transmits the same information over one of вЂnвЂ™ possible output lines. If you recall the Multiplexer tutorial, there we discussed the concept of Multiplexing. The process of getting information from one input and transmitting the same over one of many outputs is called Demultiplexing. Let us get a brief idea of demultiplexers and its types in this tutorial.

Different input/output configuration demultiplexers are available in the form of single integrated circuits (ICs).ДЄlso, there is a facility of cascading two or more DEMUX circuits, to generate multiple output demultiplexers. With the use of a Demultiplexer, data from one input can be passed to one of the many output data lines.Дemultiplexers are mainly used in Boolean function generators and decoder circuits. As an inverse to the MUX, Demux is a one-to-many circuit. The action or operation of a Demultiplexer is exactly the opposite to that of a Multiplexer. MUX is the device responsible for Multiplexing. Multiplexers are simple combinational logic circuit, which selects one of many inputs and passes it through the single output. In the previous tutorial, we learned about Multiplexers or simply MUX.
