In electronics, a multiplexer (or mux; spelled sometimes as multiplexor), also known as a data selector, is a device that selects between several analog or digital input signals and forwards the selected input to a single output line. [1]
What Are Multiplexers? A multiplexer is a combinational circuit that has many data inputs and a single output, depending on control or select inputs. For N input lines, log2 (N) selection lines are required, or equivalently, for 2^n 2n input lines, n selection lines are needed.
Learn what a multiplexer is, what it does, how it works & its applications. See the circuit diagram & truth tables for 2 to 1, 4 to 1, 8 to 1, and Arduino multiplexers.
The multiplexer, shortened to “MUX” or “MPX”, is a combinational logic circuit designed to switch one of several input lines through to a single common output line by the application of a control signal.
A multiplexer is best defined as a combinational logic circuit that acts as a switcher for multiple inputs to a single common output line. Also known as “MUX” or “MPX”, it delivers either digital or analog signals at a higher speed on a single line and in one shared device but then recovers the separate signals at the receiving end.
In simple words, a multiplexer is a digital logic device that selects one-out-of-N (N = 2 n) input data sources and transmits the selected data to a single output line. The multiplexer is also called data selector as it selects one from several. The block diagram of a typical 2n:1 multiplexer is shown in Figure 1.
A multiplexer (often abbreviated as "mux") is a digital circuit that selects one of several input signals and forwards it to a single output. It operates based on control signals to determine which input is transmitted to the output.
