1. 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 operational sections of this specification is not

implied. Exposure to absolute maximum rating conditions for extended

periods may affect reliability.
