2.1 Absolute maximum ratings
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 the conditions in table below for extended
periods may affect device reliability. Refer also to the STMicroelectronics SURE Program
and other relevant quality document.
