... 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 ADG3247 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...

... Figure 11. Location of Bus Switched in a Bus Isolation Application Hot Plug and Hot Swap Isolation The ADG3247 is suitable for hot swap and hot plug applications. The output signal of the ADG3247 is limited to a voltage that is below the V supply, as shown in Figures 6, 8, and 10. There- CC fore the switch acts like a buffer to take the impact from hot insertion, protecting vital and expensive chipsets from damage ...
