Difference Between Decoder & De Multiplexer

SNO.	DECODER	DEMULTILPLEXER
1.	Block Diagram	Block Diagram
2.	It Receives ‘n’ number of coded information and gives 2ⁿ output lines. For an ‘n’ to ‘m’ line Decode we have M ≤ 2ⁿ Outputs.	It has single input line and multiple output lines selection are used to select the input at appropriate output
3.	Types of decoder are 2 to 4 line decoder . bcd to decimal decoder etc.	Type of demultiplexers are: 1:2,1:4,1:8 ,1:16 and so on.
4.	Number of input lines is decoded are 2 or more than 2 .	Number of input line in demultiplexer are single.
5.	1:2 One Input = Two Output	Signal Input / Select Lines = Output Lines
