Note:

Stresses greater than those listed under MAXIMUM RAT-

INGS 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 ex-

tended periods may affect reliability.
