* Stresses above those listed under “Absolute Maximum Ratings” may cause perma-

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

device at these or any other condition above those indicated in the operational sections

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

extended periods may affect device reliability.
