Absolute Maximum Ratings(Note 1)
Note 1: The Absolute Maximum Ratings are those values beyond which
the safety of the dev ice cannot be guaranteed. T he device sh ould not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum ratings.
The Recommende d Operating Cond itions table will def ine the conditions
for actual device operation.
