Absolute Maximum Ratings(Note 1) Recommended Operating

Conditions

(Note 3)

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 Rat-

ings. The “Recommended Operating Conditions” table will define the condi­tions for actual device operation.
