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

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.
