... 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 the ADG438F/ADG439F features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic dischar ges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...

... MOSFET is negative. typically. During fault conditions, the leakage current into and out of the ADG438F/ADG439F is limited to a few microamps. This pro- tects the multiplexer and succeeding circuitry from over stresses as well as protecting the signal sources which drive the multi- plexer. Also, the other channels of the multiplexer will be undisturbed by the overvoltage and will continue to operate normally ...
