Push-Pull Output
Figure 25-8. Push-Pull Output I-V Characteristic at 5V
Figure 25-9. Push-Pull Output I-V Characteristic at 3V
Note:
Under DC operating conditions the Push-Pull Outputs exhibit reduced V
atures due to the 5V tolerant port structure. Under AC conditions a boost circuit provides
additional source current. If additional DC source current is required, or if V
pull-ups may be needed. DC conditions are most likely to exist when the device enters Power-
down mode.
