*Stresses greater than those listed under "Absolute Maximum

Ratings" may cause permanent damage to the device. This is

a stress rating only and functional operation of the device at

these or any other conditions above those indicated in the

operation section of this specification is not implied.

Exposure to absolute maximum rating conditions for extended

periods may affect reliability.
