* Stresses above those listed under "Absolute Maximum Ratings" may cause permanent

damage to the device. This is a stress rating only. Functional operation of the device

at these or any other conditions above those indicated in the operation sections of this

specification, is not implied. Exposure to Absolute Maximum Ratings for extended

periods may affect device reliability.
