A demultiplexer, also known as "demux", is an essential component in digital electronics. It acts as an inverse of a multiplexer, where it takes a single input and routes it to multiple outputs based on the control signal. While there isn't an excessively wide range of synonyms for "demux", some alternatives can still be used interchangeably. One commonly encountered synonym is "decoder", which accurately describes the function of demultiplexing a signal. Another synonym is "selector", highlighting its role in selecting a specific output based on the control signal. Additionally, the term "distributor" is applicable, as it distributes or separates a single input into multiple outputs in a precise manner.
