COMMENT

Stresses above those listed under “Absolute Maximum

Ratings” may cause permanent damage to the device. This

is a stress rating only; the functional operation of the device

(at these or any other conditions above those listed in the

operational sections of this specification) is not implied.

Exposure to absolute maximum rating conditions for

extended periods may affect device reliability.
