A decoder is one of many types of combinational circuits. It has multiple input lines and multiple output lines but has no selector lines like MUX and DEMUX. The decoder aids in the translation/decoding of information encoded by the encoder. As a result, it reverses the encoder's work. The decoder converts n bits of data input into two power n coded outputs.
Decoders are used in microprocessors, memory chips, and other data transfer circuits to select different I/O devices and other data transfer circuits. In a computer, a decoder is used to decode memory addresses.
The decoder looks like this:
If you can't find a 4 * 16 decoder in your area and only have a 2 * 4 decoder, you can easily implement a 4 * 16 decoder using a 2 * 4 decoder by following these steps:
2*4 Decoder has two input lines and four output lines, and it chooses one of the lines based on various input combinations.
4*16 Decoder has four inputs and sixteen outputs, and it chooses one line based on various input combinations.
Four 2*4 encoders are required to produce 16 outputs and 1 extra 2*4 decoder is required to enable the decoder when creating 4*16 decoders. As a result, a total of 5 decoders are required. But output at a time will be generated by 1 decoder only at a time.
Here, A-lines indicate MSB, and D-lines indicate LSB.
Decoder Enable Logic
This concludes that selecting Decoder (D1, D2, D3, D4) only depends on the D5 decoder.
Now the output Y0 to Y15 are generated with the various input value.

We have successfully implemented 4 * 16 decoders using five 2 * 4 decoders.
