Maximum rating

Stressing the device above the rating listed in the “Absolute Maximum Ratings” table 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.
