Electrical specifications

3.1

Absolute maximum ratings

Warning:

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 document.
