What is a Multiplexer Module?. Also known as a mux or data selector, a multiplexer device is used to forward multiple digital and analog input signals in to one single output. in forwarding multiple signals in to one output, a multiplexer allows several signals to share one device. Demultiplexers or demux operate in reverse, they are often used for cost reduction in conjunction with one another, often within communication and data links.
