The maximum total current, I(OHmax) and I(OLmax), for all outputs combined, should not exceed ±48 mA to hold the maximum voltage drop

specified.

Full drive strength of port: A resistive divider with 2 × 0.5 k

Ω between VCC and VSS is used as load. The output is connected to the

center tap of the divider.

(2)

Reduced drive strength of port: A resistive divider with 2 × 1.6 k

Ω between VCC and VSS is used as load. The output is connected to the

center tap of the divider.

(3)

The output voltage reaches at least 10% and 90% VCC at the specified toggle frequency.
