hi friends in this video we are going to learn about multiplexer so without further Ado let's start this video If you haven't subscribed to my channel then do subscribe and don't forget to press the Bell icon so you can get notifications whenever I upload a new video these are my other channels do subscribe them as well and you can also follow me on Facebook and Instagram component list circuit diagram everything is in the description below [Music] multiplexer is a combinational logic circuit designed to switch one of several input lines to a single common output line the selection is directed by a separate set of digital inputs known as select lines a multiplexer make it possible for several input signals to share one common output of a device this is the the symbol of 4 to1 multiplexer it has two select lines s0 and S1 it has four input lines from x0 to X3 and it has one output line now let's see how this 4 to1 multiplexor works when select line s0 and S1 both are zero the input X is [Music] selected when select line s0 is 1 and S1 is0 the input X1 is selected when select line s0 is 0 and S1 is 1 the input X2 is selected the when both select lines are one the input X3 is selected now let's make a logical Circuit of 4 to1 multiplexer to better understand how it works so this is The Logical Circuit of a 4 to1 multiplexer it is made with two not Gates four three input and Gates and one four input R [Music] gate [Music] [Music] [Music] [Music] now let's see a 4 to1 multiplexor chip [Music] this is an 8 to1 multiplexor chip [Music] [Music] and this one is 16 to1 multiplexor [Music] tiip [Music] [Music] so that's it for today's video I hope you have learned something new from this video for more videos like that stay tuned and I will see you you in the next [Music] [Music] video
