Note: The device is not guaranteed to function outside its

operating rating. Stresses listed under Absolute Maximum

Ratings may cause permanent damage to the device. These

are stress ratings only and functional operation of the device

at these or any other conditions outside those listed in the

operational sections of the specification is not implied.

Exposure to any absolute maximum rating for extended

periods may affect device performance and reliability.

Devices are ESD sensitive. Handling precautions are

recommended.
