*Stresses greater than those listed under "Absolute
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.
