Electrical specifications

5.1

Absolute maximum ratings

Stressing the device above the rating listed in the Table 29 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.
