Home Contact Copyright Privacy. In a similar fashion a 3-to-8 line decoder can be made from a 1-to-2 line decoder and a 2-to-4 line decoder, and a 4-to line decoder can be made from two 2-to-4 line decoders. The block diagram of the two to four decoder is shown here. Binary encoder has 2n input lines and n-bit output lines. You might also consider making a 2-to-4 decoder ladder from 1-to-2 decoder ladders. Draw the logic 74ch of a 2-bit encoder, a circuit with four input lines, exactly one of which is high at any instant, and two output lines whose 2-bit binary value tells which input is high.
