4 Maximum ratings
Stressing the device above the rating listed in Table 4: 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 Table 5: Operating and AC
measurement conditions 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.
