Multiplexer is a digital switch.It allows digital information from several sources to be rooted on to a single output line.The basic multiplexer has several data input lines and a single output line.The selection of a particular input line is controlled by a set of selection lines.Normally there are 2^N input lines and N selection lines whose bit combinations determine which input is selected.Therefore multiplexer is many into one and it provides the digital equivalent of an analog selector switch.
Show how 8 to 1 multiplexers can be cascaded to build a 64 to 1 multiplexer? To build a 64 to 1 multiplexer using cascaded 8 to 1 multiplexer, use nine 8 to 1's. Connect the first 8 to each of the. Mux is a device That has 2^n Input Lines. But Only One has Output Line. Where n= number of input selector line. Mux is A device Which is used to Convert Multiple Input line into one Output Line. At a time only one Input Line will Connect to the output line. Which Input Line Connected In Output Line is decided by Input Selector Line. 8 x 1 Multiplexer In 8 x 1 Multiplexer, 8 represents number of inputs and 1 represents output line. So three (3) select lines are required to select one of the inputs. Logic Diagram of 8 to 1 Multiplexer. VHDL code for 8:1 Multiplexer. Free download as PDF File (.pdf), Text File (.txt) or read online for free. 8:1 Multiplexer The multiplexer is a combinational circuit which accepts several data inputs and allows only one of them at a time to get through to the output. An 8-to-1 multiplexer is a digital device that selects one of the eight inputs lines to the output line by using three-bit selection line. The block diagram of 8-to-1 Mux is shown in Figure 1. A 2 n-to-1 multiplexer needs n bit selection line to select one of the 2 n inputs to the output.
