Encoder Circuit 4 To 2. It can be 4 to 2 8 to 3 and 16 to 4 line. A 4 to 2 priority encoder has 4 inputs.
If an encoder has n number of output lines then the number of input lines will be 2 n in our case the number of output lines is two n 2 hence the number of input lines should be be 2 2 4 four which is exactly the case. Hence it is said to be 4 2 encoder because of having 4 input lines and 2 output lines. The four input pins are labelled from i0 to i3 and the two output pins are labelled from o0 to o1.
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.

Circuit of 4 to 2 line encoder the above circuit diagram contains two or gates. We know in case 4 of input lines the applied input bits will be 00 01 10 11 denoting the input lines i 0 i 1 i 2 i 3. Hence it is said to be 4 2 encoder because of having 4 input lines and 2 output lines.
