Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating

only, and the functional operation of the device at these or any other conditions above those listed in the operational section of

this specification is not implied. Exposure to absolute maximum ratings conditions for extended periods may affect device

reliability.
