*Stresses at or 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 operation section of this specification is not
implied. Exposure to absolute maximum rating conditions for
extended periods will affect reliability.
