This is a stressrating only; functional operation of the device at these or anyother conditions above those indicated in the operationalsection of this specification is not implied. Exposure to absolutemaximum rating conditions for extended periods may affectdevice reliability.ESD CAUTIONESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate onthe human body and test equipment and can discharge without detection. Although this product featuresproprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energyelectrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performancedegradation or loss of functionality.Rev. 0 | Page 6 of 24
