    Shinichi-san,

    Why does your customer need to know the internal connections inside the device?  What issue are they having with the switch?

    The CDXXXXX device has a transmission gate type architecture with an NMOS FET in parallel with a PMOS FET. 

    You can see that the shape of the Ron vs input voltage has the same shape.

    For more information about different switch structures check out this application note:

    Thank you,

    Adam
