NOTE: 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 maxi-mum rating conditions for extended
periods may affect product reliability.
