Stresses above those listed in the Absolute Maximum

Ratings may cause permanent damage to the device. These

are stress ratings only and functional operation of the device at

these conditions, or at any other condition above those indicated

in the operations section of this specification, is not implied.

Exposure to Absolute Maximum Rating conditions for extended

periods may affect device reliability.
