Logic Diagram Of Priority Encoder. The block diagram of a 42 priority encoder is shown below a priority 42 encoder also has 4 inputs and 2 outputs but we will add another output called v which stands for valid bit. In this case even if more than one input is 1 at the same time the output will be the binary code corresponding to the input which is having higher priority.
Thus four inputs with two outputs are encoded based on the assigned priority to the inputs. A 4 to 2 priority encoder takes 4 input bits and produces 2 output bits. From the above expressions the simple 8 to 3 priority encoder circuit diagram can be designed through an individual or gate.
The xs in the table designate dont care.

In this case even if more than one input is 1 at the same time the output will be the binary code corresponding to the input which is having higher priority.
