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