(1) Selecting reduced drive strength may reduce EMI.
(2) 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.
(3) The maximum total current, I
(OHmax)
and I
(OLmax)
, for all outputs combined, should not exceed ±100 mA to hold the maximum voltage
drop specified.

(1) Full drive strength of port: A resistive divider with 2 × 0.5 kΩ between V
CC
and V
SS
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 kΩ between V
CC
and V
SS
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% V
CC
at the specified toggle frequency.
