Hi Allaboutcircuits,
I am using MM74C74N / MM74C00 digital chips powered gnd to 12v and analogue chips powered -/+ 12v.
I have heard that I need to use separate grounds to avoid interference.
Attached is my -/+ 12v power supply to power analogue chips. Does anyone have an idea how to power gnd to 12v supply (with bypass capacitors) that has a separate ground to power the digital chips MM74C74N / MM74C00?
