Multiplexer Circuit Diagram 8 1. The common selection lines s 2 s 1 s 0 are applied to both 1x8 de multiplexers. This abruptly reduces the number of logic gates or integrated circuits to perform the logic function since the multiplexer is a single integrated circuit.
What this tells us is that the cd4512 is an 8 1 multiplexer. The common selection lines s 2 s 1 s 0 are applied to both 1x8 de multiplexers. Logic diagram for 8 1 mux verilog code for 8 1 mux using structural modeling.
In the 8 1 mux we need eight and gates one or gate and three not gates.
The data inputs of upper 4x1 multiplexer are i 7 to i 4 and the data inputs of lower 4x1 multiplexer are i 3 to i 0. The port list will contains the output and input variables. An 8 to 1 multiplexer consists of eight data inputs d0 through d7 three input select lines s2 through s0 and a single output line y. The block diagram of 1x16 de multiplexer using lower order multiplexers is shown in the following figure.
