8 To 1 Multiplexer Using 4 To 1 And 2 To 1. 1 8. Let us derive the four inputs of 4.
For example you could connect inputs a c to cd4512 inputs c a d0 d2 and d4 d7 to gnd and d3 to d. Some of the available multiplexer ics include 74157 2 to 1 mux 78158 2 to 1 mux 74352 4 to 1 mux 74153 4 to 1 mux 74152 8 to 1 mux and 74150 16 to 1 mux. Let us derive the four inputs of 4.
16 1 multiplexer using 8 1 and 2 1 multiplexer.
Logical circuit of the above expression is given below. 1 8. For example you could connect inputs a c to cd4512 inputs c a d0 d2 and d4 d7 to gnd and d3 to d. However you can use an 8 1 mux to do any 4 input function if you have a spare inverter.
