These measurements were taken on a 4-layer board in still air, in accordance with EIA/JESD51-1.
ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy elec- trostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. Rev.
