Update,
You guys are correct! We do indeed spike up to +5V for about 3mS. I need to look into the datasheet and/or call netburner to see if this is illegal or not. Doesn't seem like you would want to do this to a 3.3V part!

That said we do have comparators(and other circuitry on the PCB) which are powered by +5V and are pulled up to 3.3V.(that seems a little silly in hindsight!) Sorry for the crummy schematic. I'm go...
