Note a: 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 conditions above
those indicated in the operational sections of this specification is not
implied. Exposure to absolute maximum rating conditions for extended
