8x3 Encoder Logic Diagram. There are different types of encoders and decoders like 4 8 and 16 encoders and the truth table of encoder depends upon a particular encoder chosen by the user. Encoder Design Applications A more useful application of combinational encoder design is a binary to 7-segment encoder.
The working and usage of 83 Encoder is also similar to the 42 Encoder except for the number of input and output pins. The decoders and encoders are designed with logic gate such as an OR-gate. An encoder is a combinational circuit that performs the reverse operation of decoder it has maximum of 2 n input lines and n output lines hence it encodes the information from 2 n inputs into an n bit code it will produce a binary code.

The above circuit diagram contains two 2-input OR gates one 4-input OR gate one 2input AND gate an inverter. The circuit diagram of 4 to 2 priority encoder is shown in the following figure. The working and usage of 83 Encoder is also similar to the 42 Encoder except for the number of input and output pins. This is what encoders and decoders are used for.
