Multiplexer Circuit 8 To 1 Multiplexer Logic Diagram. In this kind of applications multiplexers are viewed as logic function generators. In the 8 1 mux we need eight and gates one or gate and three not gates.
The data inputs of upper 8x1 multiplexer are i 15 to i 8 and the data inputs of lower 8x1 multiplexer are i 7 to i 0. In this case however we have a 4 input function. The port list will contains the output and input variables.
Earlier we noted that we can use the cd4512 s 8 1 multiplexer to implement any 3 input logical function.
The data inputs of upper 8x1 multiplexer are i 15 to i 8 and the data inputs of lower 8x1 multiplexer are i 7 to i 0. We won t go into this in detail here. From the above boolean equation the logic circuit diagram of an 8 to 1 multiplexer can be implemented by using 8 and gates 1 or gate and 7 not gates as shown in below figure. The port list will contains the output and input variables.
