Best Brushless Motors The basic design of demultiplexer. Aug 8, 2019 - There are mainly four types of Multiplexer mostly used. For example, an 8-to-1 multiplexer can be constructed by cascading two 4-to-1 and one 2-to-1 multiplexer. So depends on the combination of select inputs, input data is passed through the selected gate to the associated output. The block diagram of 1:4 DEMUX is shown below. Problem Solution. Its characteristics can be described in the following simplified truth table. Also, the facility of cascading two or more IC circuits helps to generate multiple output demultiplexers. When S 1 S 0 = 10, the third AND gate gets enabled, which will drive the data input D to the output terminal Y 2. Best Gaming Headsets The outputs of upper 1x4 De-Multiplexer are Y 7 to Y 4 and the outputs of lower 1x4 De-Multiplexer are Y 3 to Y 0.

For example, if the selection lines AB = 10, output D 2 will be the same as the input value E, while all other outputs are maintained at 1. With the use of a demultiplexer , the binary data can be bypassed to one of its many output data lines. Home / Keyword: 1 to 8 demultiplexer. Digital Multimeter Kit Reviews Here is an example of an 8:1 MUX from 2:1 MUX without using a 2:1 MUX at the output. Similarly, other outputs are connected to the input for other two combinations of select lines. 1-to-16 Demultiplexer Working: A demultiplexer obtains in data from one line and directs this to any of its N outputs depending upon the status of the selected inputs. Let’s write the truth table for this demux. b + log2 n ≤13 b n s 1 8 3 (12) 8 input 1 bit 74x151 2 4 2 (12) dual 4 input 2 bit 74x153 4 2 1 (13) quad 2 input 4 bit 74x157 n data inputs b bits per input s select inputs 12 of 31 Truth table of 74x151 Truth table for 74x151 8-input, 1-bit multiplexer In case if more than 16 output pins are needed, then two or more demultiplexer ICs are cascaded to fulfill the requirement. In the 1: 4 demultiplexer circuit, the data input line goes to all of the AND gates. The output data lines are controlled by n selection lines. The device features two input enable (E0 and E1) inputs. 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.
