A circuit diagram of this encoder is shown below. 8 – to – 3 Priority Encoder or Octal – to – Binary Priority Encoder. The truth table of an octal – to – binary priority encoder is shown below.

A 4-to-2 priority encoder takes 4 input bits and produces 2 output bits. In this truth table, for all the non-explicitly defined input combinations (i.e. inputs containing 2, 3, or 4 high bits) the lower priority bits are shown as don't cares (X).

Encoder truth tables and circuit diagrams are used in electronics engineering to help explain how a particular encoder works. These diagrams can be used to identify the input and output relationships of a circuit as well as the number of possible states of the encoder.

In the following figure, a typical 4-to-2 Encoder along with its truth table has been shown. The output lines (Q0 & Q1) output a binary code to encode four input lines (D0, D1, D2, & D3). When D0 is “HIGH” then both outputs are “LOW”, similarly, a “HIGH” state of D1 input enables only Q0 to “HIGH”, and other inputs are encoded, accordingly.

For example, a 4-to-2 encoder has 4 inputs and produces a 2-bit output code, while an 8-to-3 octal-to-binary encoder has 8 inputs and 3-bit outputs. Encoders are implemented using OR gates based on the truth table outputs.
