3.3.11 Digital Output
The outputs are Open-Drain type with no internal pull-up resistor which also be used to
control a relay. It means that the user has to connect a pull-up resistor or a relay coil
between the output pin and any positive voltage to generate a correct output. Each output
can drive a continuous current of 0.2A.
The electrical conditions are:
