Background. This is also called a 1 of 8 decoder, since only one of eight output lines is high for a particular input combination. The circuit diagram of 2 to 4 decoder is shown in the following figure.

Enable inputs must be on for the decoder to function, otherwise its outputs assume a single disabled output code. A decoder takes input lines and has output lines. A binary decoder gives output at only one of the output lines depending on the physical.

4 channel multiplexer using logic gates the symbol used in logic diagrams to identify a multiplexer is as follows.

In the one−of−eight decoding or demultiplexing mode, the addressed output follows the state of data in with all other outputs in the low state. 1 bit corresponding to the value of the binary input number is set to 1. It is the reverse process of an encoder. The three enable inputs are provided to ease cascade connection and application of address decoders for memory systems.
