What is Demultiplexer?
The decoder is a combinational circuit that has 1 input and M outputs and depending on the inputs at the selection lines, the input of the demultiplexer appears at one of the outputs. That's why it is also called, one to many device.
If the multiplexer has N selection lines then total 2 ^ N outputs can be distinguished using the N selection lines.
Depending on the number of selection lines and outputs, there are different types of Demultiplexers.
e.g 1 to 2 Demultiplexer, 1 to 4 Demultiplexer, 1 to 8 Demultiplexer etc.
Applications of Demultiplexer:
In time-division multiplexing applications, the multiplexer and demultiplexer are used together. The multiplexer is used on the transmitter side, while the demultiplexer is used on the receiver side.
It can also be used for Serial to Parallel Conversion.
And since the design of Demultiplexer is similar to the Decoder, it can also be used in all the applications where the decoder is used.
The Decoder as Demultiplexer:
In this video, how to use the decoder as a demultiplexer is explained. And at the later part of the video, using the Demultiplexer, how to implement the different Boolean Functions is also explained.
This video will be helpful to all the students of science and engineering in understanding what is demultiplexer, its applications, and how to use demultiplexer for implementing different logic circuits.

hello sir, at 8:15 , instead of using a 1*2 demux , we can simply use enable of both 1*8 demux by connecting the E1 to inverted S3 and E2 directly to S3, as we did in mux designing.
and sir one more doubt, like in logic implementation , if we want to implement a 4 bit logic using mux, we can use a mux with 2 , 3 , 4 select lines , all can implement the logic,
so can we do the same in demux or decoder also or shall we need same number of select lines or input lines as the number of variable in the expression?
Nice video and useful information. 👍
Thank you sir 🙏 ☺️ appreciate all your lectures from Nepal 🇳🇵 🙏 😊
Iam having my exams tomorrow and Iam seeing this video now Hope that I can attend all the questions from this video
brother 😇💜
Need a full explained video on Data transmission through MUX And Demux where input data is given in ASCII code
A lot of thanks to you sir, 🙏🙏🙏😌
Very very nice 👍
Thank You again and again :)
Please help me with this: Why two different terms than, Decoder and DeMux, when both are interchangeable?
Both are used for different purposes. One is used for decoding, another one is used for demultiplexing the inputs. The different names are based on their functionality.
@@ALLABOUTELECTRONICS Based on functionality, Ok it makes sense now :)
Super video
At 4:48 you said , demux input 'I' is connected to decoder .There are two possibilities '1' and '0' .As you said if input is logic high (1) then it works well but if logic 0 means then the decider itself not works irrespective of the input given to decoder then how the input I is appear depending on the input combination given to decoder .Please clear this doubt Sir .
when the input I (Enable input ) is 0 then of course all the outputs will be 0. (please see at 5:33). But if the changing with the time (1 and 0 with the time) then you will get that input at the specific output pin. If you consider a static input which remains 0 then yes, all the outputs will appear to be logic '0' level. But in reality, the input to the logic circuit is continuously changes between 1 and 0. So, that output will appear at the specific pin depending on the value of A, B and C. I hope, it will clear your doubt.
@@ALLABOUTELECTRONICS Thank you for your reply Sir .Now it's clear .
🖐 can we create the ' 1 to 8 demultiplexer ' circuit diagram using ' 1 to 4 demultiplexer ' and ' 1 to 2 demultiplexer '?
Yes, definitely. You require two 1 to 4 demultiplexer and one 1 to 2 multiplexer.
Sir please can the multiplexer be used to add more than 3 bits addition
Yes, you can do so. But the thing is, after addition you will have two outputs. The sum and carry output. If you implement it using the multiplexer, then you can generate only one of them. To generate two outputs, you need one more multiplexer.
