Note a:

Stresses greater than those listed under “Absolute Max-

mum Ratings” may cause permanent damage to the

device. This a stress rating only, and functional operation

of the device at 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.
