    Is anybody familiar with a FET driver with outputs that can be tri-stated? I need to drive some long 12V signal lines from 3.3V or 5V logic, plus also disconnect the drivers and use the signal lines as inputs. It looks like the contemporary function that's a good fit is a low-side FET driver. I'm looking at the ST SRK2000, which would probably be perfect if the "off" state controlled by the EN pin is Hi-Z. If "off" means "ground the FET gate," then I'll have to keep looking.
