A demultiplexer is a device that
Show Hint
Think of a demultiplexer (DEMUX) as the opposite of a multiplexer (MUX). A MUX selects one of many inputs to route to a single output (many-to-one), while a DEMUX takes a single input and sends it to one of many outputs (one-to-many).

- Encode multiple inputs into one output
- Decode binary to decimal
- Store binary information
- Route a single input to multiple outputs

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
A demultiplexer, often abbreviated as DEMUX, is a combinational logic circuit.
Its primary function is to take a single input line and route it to one of several possible output lines.
The specific output line to which the input is routed is determined by the value of a set of select lines.
It is essentially a one-to-many switch.
Therefore, the correct description is that it routes a single input to multiple outputs.
