NOTE: 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 Charac-
teristics is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect product reliability.
