Difference between Multiplexer and Decoder
1. Multiplexer :
Multiplexer is a data selector which takes several inputs and gives a single output.In multiplexer we have 2n input lines and 1 output lines where n is the number of selection lines.
2. Decoder :
Decoder is a logic circuit which n input lines into m output lines.Decoders are called as min-term and max-term generators because for each of the input combinations, exactly one output is true.
Difference between of Multiplexer and Decoder :
S.NO. |
Multiplexer |
Decoder |
1. |
MUX accepts several inputs and allow only one data output. |
It takes n input binary code and convert it into a corresponding outputs. |
2. |
Select line are used to select data inputs and allow only one of them. |
Enable inputs are used to control the operation of the decoder. |
3. |
It can be used in data routing and waveform generation. |
Application of decoder is in Decimal to BCD encoder. |
4. |
Multiplexer converts the unary code into binary code |
Decoder converts binary code into unary.. |
