Hi all
Just a general question here, please help me try understand whats best to do in a situation like this:
I am using a 4511 IC to control digits 1-6. My inputs are six individual sing pole switches. Obviously the 4511 IC has 4 inputs, truth table can be found here: **broken link removed**
Here is a diagram of how I wanted to wire the circuit up...
**broken link removed**
Problem I can see here is that the inputs are all bridged, so when one switch is closed it will set inputs A,B,C to '1'.... which is not what I want obviously. How do I isolate each switches inputs? Diodes? Resistors?
Help please.
Thanks
