So depends on the combination of select inputs, input data is passed through the selected gate to the associated output. When calculations are carried out electronically they will usually be in binary or twos complement notation, but the result will very probably need to be displayed in decimal form. 1. The basic design and working of a DEMUX can be understood from the following example. Examples: binary to octal conversion using 3 to 8 decoder, BCD to decimal conversion using 4 to 10 decoder, binary to hexadecimal conversion using 4 to 16 decoder, etc. The 1-to-2 Line Decoder/Demultiplexer The opposite of the multiplexer circuit, logically enough, is the demultiplexer . Consider a 1-to-4 line demultiplexer. 1-to-8 DEMUX using Two 1-to- 4 Demultiplexers, Implementation of Full Subtractor Using 1-to-8 DEMUX, Selecting different IO devices for data transfer, Depends on the address, enabling different rows of memory chips, Boolean function implementation (as we discussed full subtractor function above). The action or operation of a demultiplexer is opposite to that of the multiplexer. Here, for constructing the demultiplexer circuit, 7404 IC for NOT gate and 7411 IC for AND gates are used.

This description sounds similar to the description given for a decoder, but a decoder is used to select among many devices while a demultiplexer is used to send a signal among many devices. of inputs=N=4 No. In this, m selection lines are required to produce 2m possible output lines (consider 2m = n). From the truth table, the demultiplexer can be constructed using AND gates and NOT gates. The truth table can easily be modified for muxes that handle different numbers of inputs by adding or removing control input columns. It distributes one input line to one of 8 output lines depending on the combination of select inputs. The two selection lines enable the particular gate at a time. Pictures: (Wikipedia CC BY-SA 2.5) Explanation: Before we start implementing we first need to check if it is common anode or common cathode. In this type of decoders, decoders have two inputs namely A0, A1, and four outputs denoted by D0, D1, D2, and D3. Depending on the combination of input signal and control signals, there be. For instance, decimal number ‘1’ would control a blend of b & c. The second step is the truth table design by listing the display input signals-7, equivalent four-digit binary numbers as well as decimal number.
