Note:

Stresses greater than those listed under 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 condi-

tions 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.
