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 Character-
istics is not implied. Exposure to absolute maxi-
mum rating conditions for extended periods may
affect product reliability.
