Absolute Maximum Ratings
(Note 2)
Note 2:
The
Absolute Maximum Ratings
are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum ratings.
The
Recommended Operating Conditions
table will define the conditions
for actual device operation.
