1. Stresses greater than those listed under ABSOLUTE MAXIMUM RAT-

INGS 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 operational sections of this specification is not implied.

Exposure to absolute maimum rating conditions for extended periods may

affect reliabilty.
