Digital input - Connect to GND to activate, or leave
floating (or unconnected) to deactivate.
Digital output - Uses an opendrain NFET transistor
with the source connected to GND. If used with
an external relay, a diode must be connected
in parallel with the load, for protection against
voltage transients.
Min input = 0V DC
Max input = + 40V DC
Max load = 100mA
Max voltage applied = + 40V DC
