3-Line to 8-Line Decoder

3 to 8 line decoder demultiplexer is a combinational circuit that can be used as both a decoder and a demultiplexer. IC 74HC238 decodes three binary address inputs (A0, A1, A2) into eight outputs (Y0 to Y7). The device also has three Enable pins. The same combination is used as a demultiplexer.
