DD
= 3.0 to 5.5 V unless otherwise specified
Note: 1. Common input and output ports with open-drain output specifications are specified for the state with the output N-channel transistor turned off.
These pins cannot be used for input when the CMOS output specification option is selected.
2. Common input and output ports with open-drain output specifications are specified for the state with the output N-channel transistor turned off.
Ratings for pull-up output specification pins are stipulated for the output pull-up current IPO. These pins cannot be used for input when the CMOS
output specification option is selected.
3. Stipulated for CMOS output specifications with the output N-channel transistor in the off state. (This also applies to P8 when P-channel open drain
is selected.)
4. Stipulated for pull-up output specifications with the output N-channel transistor in the off state.
5. Stipulated for P8 with CMOS output specifications.
6. Stipulated for open drain output specifications with the output N-channel transistor in the off state.
7. Stipulated for open drain output specifications with the output P-channel transistor in the off state.
