Demultiplexern

Demultiplexern is a term that appears to refer to a demultiplexer, a digital logic device used to route a single input signal to one of several outputs. In operation, data is applied to a common input, while a set of selector lines encodes which output will carry the data at a given moment. The remaining outputs are typically inactive or held in a defined state, depending on the circuit design.

Commonly called a demultiplexer (demux), the device performs the inverse function of a multiplexer. A 1-to-N demultiplexer sends the input to exactly one of N outputs, guided by binary select bits. Variants include 1-to-2, 1-to-4, and 1-to-8 configurations; more broadly, any N can be implemented using a decoder as part of the circuit. Many demultiplexers include an enable input to gate operation.

In digital systems, demultiplexers are used to route data signals to different destinations, implement data distribution, control memory addressing, or select channels in time-division multiplexing schemes. They are fundamental building blocks in data routing, bus control, and switching networks.

Important considerations include propagation delay, fan-out, and logic-level compatibility between inputs and outputs. Some devices provide active-high outputs, others active-low, and enable behavior that affects whether the input is transparently routed.

Note: The term Demultiplexern is not standard in English; the conventional term is demultiplexer. If encountered in a specific context, consult the relevant datasheet or terminology guide for that usage.
