Multiplexer – Wikipedia
Conversely, a demultiplexer or demux is a device taking a single input signal and selecting one of many data-output-lines, which is connected to the single input. While this is mathematically correct, a direct physical implementation would be prone to race conditions that require additional gates to suppress.
Since digital logic uses binary values, powers of 2 are used 4, 8, 16 to maximally control a number of inputs for the given number of selector inputs.
High speed signals were usually active low, for much the same reason. I have a doubt in the demultiplexer section. I understand how it works.
So you can use a 47 kilohm resistor to pull up drops 1. Inputs were pulled high by default, and demuliplexor pulled low when necessary, to save power. This is the image of a 1 to 16 demux.

Often, a multiplexer and demultiplexer are combined together into a single piece of equipment, which is conveniently referred to as a “multiplexer”. In analog circuit design, a multiplexer is a special type of analog switch that connects one signal selected from several inputs to a single output.
Demultiplexor by HENRY FARINANGO on Prezi
Any Boolean function of n variables and one result can be implemented with a multiplexer with n selector inputs. The binary value expressed on these selector pins determines the selected input pin.
Branch prediction Memory dependence prediction. But when we try to implement a demultiplexer using a TTLthis is the truth table that is given in the book: Sign up using Facebook. Post as a guest Name. In electronicsa multiplexer or mux is a device that combines several analog or digital input signals and forwards them into a single output line.
Is the hardware implementation circuit different than the one explained in theory? Tomasulo algorithm Reservation station Re-order buffer Register renaming. They forward the data input to one of the outputs depending on the values of the selection inputs.
This carried through to the input current requirements: Both circuit elements are needed at both ends of a transmission link because most communications systems transmit in both directions.
Demultiplexers take one data input and a number of selection inputs, and they have several outputs. One use for multiplexers is economizing connections over a single channel, by connecting the multiplexer’s single output to the demultiplexer’s single input. The actual implementation of the chosen ic has active low outputs.
Other common sizes are 4-to-1, 8-to-1, and to Sign up using Email and Password.
