I have been racking my braintrying to figure out how to make a circuit to produce a one and only one output. I would like to do this with analog components or a few (2-3) discrete ICs, as they are easier for me to obtain. Here's the jist:
Button A is pushed, output A on, all others off
Button B is pushed, output B on, all others off (including A)
Button C is pushed, output C on, all others off (including B and A)
The initial circuit will be for six inputs/outputs, but I would like to make it scalable so more inputs/output can be added later.
In addition, I also need to know when any button is pushed. This output would be momentary. I thinking of a multiple input or gate, or in the case of analog parts, a series of diodes connected to a resistor and transistor forming the analog OR gate.
