*Stresses above those listed under Absolute Maximum Ratings may cause
permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions above those listed in
the operational sections of this specification is not implied. Exposure to
absolute maximum ratings for extended periods of time may affect device
reliability.
