Electrostatic Discharge Sensitivity
This product has been tested for electrostatic nsitivity to the limits stated in the specifications. However, NVE recommends that all integrated circuits be handled with appropriate care to avoid damage. Damage caud by inappropriate handling or storage could range from performance degradation to complete failure.
