Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These ratings are
stress specifications only and functional operation of the device at these or any conditions beyond those listed in the DC Character-
istics or AC Characteristics is not implied. Exposure to absolute maximum rating conditions for extended periods may affect product
reliability.
