Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These ratings
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.
