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 (32V max.) to generate a correct output. Each output
can drive a continuous current of 0.2A.
The electrical conditions are:
