Electrical specifications

2.1

Absolute maximum ratings

Stressing the device above the rating listed in the Table 3: 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.
