3.1.2 Recommended operating conditions
The total output current is the sum of all the currents flowing through all the applicable ports. The total average current is
an average value measured over 100 ms. The total peak current is the peak value of all the currents.
2: The peak output current is the peak current flowing in each port.
3: The average output current IOL(avg), IOH(avg) in an average value measured over 100 ms.
