* “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They
are not meant to imply that the device should be operated at these limits. The tables of “Recommended Operating
Conditions” and “Electrical Characteristics” specify conditions for device operation.
