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.
