The requirement of the device is the following.
-------------------------

    Hi Kensuke,

    Sorry for the late reply. 

    There's few device of 5V supply which meets your needs. Is it necessary to use 5V power supply?

    Many of the 3.3V parts are designed recently, so these device usually have high ESD ratings.  If you can use 3.3V supply, there would be more choices.

    For example, SN65HVD1470, SN65HVD70, both have up to 12kV contact discharge and up to 4kV FTB.

    Thank you very much!

    Best regards,

    Hi Vio-san,

    Thank you for your support.
    Although I heard 5V is necessary, I will check again.
