Stressesabovethoselistedunder“AbsoluteMaximumRatings”maycausepermanentdamage
to the device. These are stress ratings only, and functional operation of the device at these or
any other conditions outside of those listed in the operational sections of this specification is not
implied. Exposure to any absolute maximum rating for extended periods may affect device
performance and reliability.
