Note: Except for the rating ”Operating Temperature Range”, stresses above those listed in the Table ”Absolute Maximum Ratings” may
cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other conditions above
those indicated in the Operating sections of this specification is not implied. Exposure to Absolute Maximum Rating conditions for extended
periods may affect device reliability. Refer also to the SGS-THOMSON SURE Program and other relevant quality documents.
