How do you convert a 1x4 demux to 1x8 demux? - Answers

To convert a 1x4 demultiplexer (demux) to a 1x8 demux, you can cascade two 1x4 demuxes. Connect the output of the first 1x4 demux, which will have four outputs, to the select lines of a second 1x4 demux. The first demux's select lines determine which of its four outputs is active, while the second demux further divides that selected output into eight, effectively achieving the desired 1x8 demux functionality.
