* This may be limited by the requirements of any relays that
are driven from this supply. The minimum supply voltage =
the minimum relay pull-in voltage at the highest allowable
ambient temperature.
** This is the maximum allowable current per relay, which is
limited by the sink capabilities of devices on the board.
