NOTE: Stresses above those listed under "Absolute Maximum
Ratings" may cause permanent damage to the device. These are
stress ratings only and functional operation of the device at these or
any other conditions above those indicated in the operational sections
of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.
