Hi - Been trying to read up on this but TBH can't find much - maybe I'm using the wrong search terms? As I understand it, if a microprocessor (or any other IC?) is un-powered but it's inputs/outputs are held high by some external device, then those inputs/outputs can latch up and even be permanentl…

parasitic power i/o latchup/damage?
