AC Timing
NOTES:
Timing Diagrams
4. Typical values are for AVCC = VCC = 2.7V to 5.0V, T
5. T
6. When pin is open, voltage is pulled up through current source to VCC.
7. Limits should be considered typical and are not production tested.
8. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization
NOTE:
