ABSOLUTE MAXIMUM RATINGS
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.
