The very simple circuit for a hardware debugger @ https://sites.google.com/site/wa... includes a FET as a high side switch.
My reading of the circuit is that the FET terminals are correctly labeled but that the symbol is reversed. i.e. the symbol leg labeled Drain is actually the the Source.
I think my understanding is correct but assume that having been around for a few years the diagram should be correct.
Any confirmation or straightening out my poor FET knowledge would be appreciated.
