ATTENTION:
Electrostatic
sensitive device.
Requires special
handling.
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/or test equipment that can discharge without detection. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality during product handling.
