Notes 1. Value of current at which the device operation is guaranteed even if the current flows from the V
DD and
EV
DD pins to an output pin.
2. Do not exceed the total current value.
3. Specification under conditions where the duty factor ≤ 70%.
The output current value that has changed to the duty factor > 70% the duty ratio can be calculated with the
following expression (when changing the duty factor from 70% to n%).
• Total output current of pins = (I
OL × 0.7)/(n × 0.01)
<Example> Where n = 80% and I
OL = 40.0 mA
Total output current of pins = (40.0 × 0.7)/(80 × 0.01) ≅ 35.0 mA
However, the current that is allowed to flow into one pin does not vary depending on the duty factor. A
current higher than the absolute maximum rating must not flow into one pin.
Remark Unless specified otherwise, the characteristics of alternate-function pins are the same as those of the port
pins.
