Note 1. Device operation is guaranteed at the listed currents even if current is flowing from the V
DD
pin to an output
pin.
Note 2. The value for maximum total current must not be exceeded.
Note 3. The listed currents apply when the duty cycle is no greater than 70%. Use the following formula to calculate
the output current when the duty cycle is greater than 70%, where n is the duty cycle.
Total output current from the listed pins = (I
OH
× 0.7)/(n × 0.01)
Example when n = 80% and I
OH
= –10.0 mA
Total output current from the listed pins = (–10.0 × 0.7)/(80 × 0.01) ≅ –8.7 mA
Total output current from the listed pins = (I
OL
× 0.7)/(n × 0.01)
Example when n = 80% and I
OL
= 10.0 mA
Total output current from the listed pins = (10.0 × 0.7)/(80 × 0.01) ≅ 8.7 mA
Note that the duty cycle has no effect on the current that is allowed to flow into a single pin. A current
higher than the absolute maximum rating must not flow into a single pin.
Note 4. Device operation is guaranteed at the listed currents even if current is flowing from an output pin to the V
SS
pin.
Caution P00, P01, P03 to P07, P22, and P41 do not output high level in N-ch open-drain mode.
