Logic Diagram Of 8 To 1 Line Multiplexer

The same selection lines s 2 s 1 s 0 are applied to both 8x1 multiplexers.
Logic diagram of 8 to 1 line multiplexer. Here s the module for and gate with the module name and gate. Depending on the select lines combinations multiplexer decodes the inputs. All we have to do is wire the d0 to d7 inputs to the 0s and 1s we wish to appear on the q output as illustrated by the desired truth table. In the 8 1 mux we need eight and gates one or gate and three not gates.
The below figure shows the block diagram of an 8 to 1 multiplexer with enable input that enable or disable the multiplexer. The block diagram of 16x1 multiplexer is shown in the following figure. Basically we can use our 8 1 multiplexer to implement any 3 input logical function. Start defining each gate within a module.
We can implement 16x1 multiplexer using lower order multiplexers easily by considering the above truth table. Low input current of 1 µa max 8 line to 1 line multiplexers can perform as. Which input line connected in output line. At a time only one input line will connect in the output line.
The port list will. The strobe g input must be at a low logic level to enable the inputs. In 4 1 mux there will be 4 input lines and 1 output line. But only one have output line.
8 to 1 multiplexer mux logic diagram and working ankit jat. The data inputs of upper 8x1 multiplexer are i 15 to i 8 and the data inputs of lower 8x1 multiplexer are i 7 to i 0. Mux is a device which is used to convert multiple input line into one output line. Decide which logical gates you want to implement the circuit with.
And to control which input should be selected out of these 4 we need 2 selection lines. It is possible to make simple multiplexer circuits from standard and and or gates as we have seen above but commonly multiplexers data selectors are available as standard i c. 2 to 1 multiplexer 1select line 4 to 1 multiplexer 2 select lines 8 to 1 multiplexer 3 select lines 16 to 1 multiplexer 4 select lines details circuits diagrams schematic designs truth tables and application of different kind of muxes are as follow. Packages such as the common ttl 74ls151 8 input to 1 line multiplexer or the ttl 74ls153 dual 4 input to 1 line multiplexer.
An 8 to 1 multiplexer consists of eight data inputs d0 through d7 three input select lines s2 through s0 and a single output line y. In this article we will discuss the designing of 4 1 mux with the help of its circuit diagram input line selection diagram and truth table.
