Electrical specifications

2.1

Absolute maximum ratings

Stressing the device above the ratings listed in the “Absolute maximum ratings” tables 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 this section for extended

periods may affect device reliability. Refer also to the STMicroelectronics SURE Program

and other relevant quality documents.

Note:

The circuit is ESD protected according to MIL-STD-883C.
