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 sec-

tions of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
