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