*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 operation sections of the specifications is not implied.

Exposure to Absolute Maximum Rating conditions for extended periods

may affect device reliability.
