*Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress

rating only. Functional operation of the device at these or any other condition above those indicated in the operational sections of

this specification, is not implied. Exposure to Absolute Maximum Ratings for extended periods may affect device reliability.

During manufacturing, testing and shipment we take great care to protect our products against potential

external environmental damage such as Electrostatic Discharge (ESD). Although our products have ESD

protection circuitry, permanent damage may occur on products subjected to high-energy electrostatic

discharges accumulated on the human body and test equipment and can discharge without detection.

Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of

functionality during product handling.
