A demultiplexer is used to :

The correct answer is Option 1.

Key Points

• A demultiplexer is a digital logic circuit that takes a single input signal and routes it to one of several output lines.
• It is often used in applications where data needs to be sent to one of many devices.
• The selection of the output line is controlled by additional input lines called selection lines or control signals.
• A demultiplexer can be thought of as a single input, multiple output switch.
• Common applications of demultiplexers include data routing, communication systems, and memory addressing.

Additional Information

• Demultiplexers are the reverse of multiplexers, which combine multiple inputs into a single output.
• In digital communication, demultiplexers are used to separate time-division multiplexed (TDM) signals.
• They can also be used in combination with multiplexers to implement complex data routing systems.
• Demultiplexers can be implemented using logic gates such as AND, OR, and NOT gates.
