How many select lines are required for a 1-to-8 Demultiplexer?
A demultiplexer, or demux, is a combinational logic circuit designed to take a single input line and route it to one of several output lines. The specific output line to which the input is routed is determined by the select lines. A 1-to-8 demultiplexer has one input, eight outputs, and a set of select lines that determine which output line the input is sent to.
8 = 2m
To find m, we take the logarithm base 2 of both sides:
log2(8) = m
Since 23 = 8, we find that:
m = 3
Therefore, 3 select lines are required for a 1-to-8 demultiplexer.
