Electrical characteristics

Stressing the device above the ratings 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 are not implied. Exposure to absolute maximum rating conditions for

extended periods may affect device reliability.
