Note:

Stresses greater than those listed under MAXI-

MUM 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.
