Hello,

I have a configuration (16f877) in witch the PIC receives 5V signal to its A port. I noticed that when the PIC is off and powersupply is out of the wall and signal source is running, the PIC pins are conducting state. I have a LED another side of the PIC (port b pin driving it) that lights up according to the 5 bit parallel signal to port A. This got me worry for the device, is this healthy? It is still working so it wont break atleast right away of that, but im still concerned about it.
