Note 1: 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.
