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.

ATTENTION:

Electrostatic

sensitive device.

Requires special

handling.
