Note:
1. Capacitance values are guaranteed by design and characterization, and are not tested.
2. Maximum input high voltage for short duration (not continuous operation).
3. Additional input current may be attributed to the Level Protection Keeper Lock circuity. For details, see Section 7.9 on Page 38.
