ABSOLUTE MAXIMUM RATINGS
NOTE: Stresses beyond those listed under Absolute
Maximum Ratings may cause permanent damage to the
device. These ratings are stress specifications only. Func-
tional operation of product at these conditions or any con-
ditions 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 prod-
uct reliability.
