Output driving current
The GP I/Os have different drive capabilities:
●

In the application, the user must limit the number of I/O pins which can drive current to
respect the absolute maximum rating specified in

Subject to general operating conditions for V
O2 outputs can sink or source up to +/-2 mA.
O4 outputs can sink or source up to +/-4 mA.
outputs can sink or source up to +/-8 mA or can sink +20 mA (with a relaxed V
