Notes: 1. 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 STMicroelectronics SURE Program and other

relevant quality documents.
