One example of an analog multiplexer is the source control on a home stereo unit that allows the user to choose between. Since you have mentioned only 4x1 mux, so lets proceed to the answer. Few types of multiplexer are 2to1, 4to1, 8to1, 16to1 multiplexer. A multiplexer or mux is a combinational circuits that selects several analog or digital input signals and forwards the selected input into a single output line. Also, in clock gating checks at a multiplexer, we discussed the conditions wherein a normal multiplexer can be used to propagate a clock without any glitches. The max4734 is a low onresistance, lowvoltage, 4channel cmos analog multiplexer that operates from a single 1. I cannot seem to understand how in the attached diagram, they went from the 41 multiplexer to the 21 multiplexer. The figure below shows the block diagram of a 4to1 multiplexer in which the multiplexer decodes the input through select line. The select lines determine which input is connected to the output, and also to increase the amount of data that can be sent over a. The four input bits are namely 0, d1, d2 and d3, respectively.
