A decoder is a combinational circuit. It has n input and to a maximum m = 2n outputs. Decoder is identical to a demultiplexer without any data input.
DECODER
A
decoder is a combinational circuit. It has n input and to a maximum m = 2n
outputs. Decoder is identical to a demultiplexer without any data input. It
performs operations which are exactly opposite to those of an encoder.

Examples
2
to 4 Line Decoder.
The
block diagram of 2 to 4 line decoder is shown in the fig. A and B are the two
inputs where D through D are the four outputs. Truth table explains the
operations of a decoder. It shows that each output is 1 for only a specific
combination of inputs.
