Notes 1. value of current at which the device operation is guaranteed even if the current flows from the VDD pin to an
output pin.
2. However, do not exceed the total current value.
3. The output current value under conditions where the duty factor ≤ 70%.
If duty factor > 70%: The output current value can be calculated with the following expression (where n
represents the duty factor as a percentage).
• Total output current of pins = (I
OH × 0.7)/(n × 0.01)
<Example> Where n = 80% and I
OH = −10.0 mA
Total output current of pins = (−10.0 × 0.7)/(80 × 0.01) ≅ −8.7 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.
4. 24-pin products only.
Caution P10 to P12 and P41 for 20-pin products, P01, P10 to P12, and P41 for 24-pin products, and P00, P10
to P15, P17, and P50 for 30-pin products do not output high level in N-ch open-drain mode.
Remark Unless specified otherwise, the characteristics of alternate-function pins are the same as those of the port
pins.
