Stresses above those listed under Absolute Maximum Ratings

may cause permanent damage to the device. This is a stress rat-

ing only and functional operation of the device at these or any

other conditions above those indicated in the operational sec-

tion of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect

device reliability.
