Notes on D.C. Characteristics:

1. Negative currents flow into the device (sinking), positive currents flow out of the

device (sourcing).

2. Output pin or bidirectional pin. Voh not measured on Open Drain outputs.

3. Input pin or bidirectional pin without internal pull-up resistor.

4. Input pin or bidirectional pin with internal pull-up resistor.
