Multiplexers are part of computer systems to select data from a specific source, be it a memory chip or a hardware peripheral. A computer uses multiplexers to control the data and address buses, allowing the processor to select data from multiple data sources. In digital communications, multiplexers allow several connections over a single channel by connecting the multiplexer''s single output to the demultiplexer''s single input (time-division multiplexing). The imag
