* Notice
Stresses above 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 device reliability.
