Hi All ,
i'm trying a circuit using 74151 Multipliexer , on protous , actaully i have a problem,
when i try to simulate it , nevertheless the ABC selection i select the output is same , no differance ,
i think the enable port have to be connected to the Ground , and i did that , but no way the output doesn't change when i change the switch case.
here is the schematic , and please tell me what's wrong , i have just deleted the E port wiring ,
thank you
