time for which current is not output is 0.3 × t, where t is a specific time). The total output current of the pins
at a duty factor of other than 70% can be calculated by the following expression.

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.
