This is a stress rating only; functional operation of the device at these or any other conditions above those listed in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Only one absolute maximum rating may be applied at any one time. 1 Overvoltages at S or are clamped by internal diodes. Current should be limited to the maximum ratings given. ES CAUTION ES (electrostatic discharge) sensitive device. Electrostatic charges as high as 4 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ES protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ES precautions are recommended to avoid performance degradation or loss of functionality. Rev. Page 6 of 16
