8x1 Mux Logic Diagram. Multiplexers are not limited to just switching a number of different input lines or channels to one common single output. It uses a cd4512 which has a b and c inputs that selects one of eight data inputs d0 to d7 and presents the state of the selected input on the q output.
It uses a cd4512 which has a b and c inputs that selects one of eight data inputs d0 to d7 and presents the state of the selected input on the q output. There are also types that can switch their inputs to multiple outputs and have arrangements or 4 to 2 8 to 3 or even 16 to 4 etc. For example consider the below logic diagram to implement the ex or function of three inputs.
There are 3 variables in the given expression hence 2 n 2 3 8.
It will work for any logic combination of the three inputs and it s easy to go from the truth table to the circuit diagram. It uses a cd4512 which has a b and c inputs that selects one of eight data inputs d0 to d7 and presents the state of the selected input on the q output. There are 3 variables in the given expression hence 2 n 2 3 8. The symbol used in logic diagrams to identify a multiplexer is as follows.
