    Hasebe-san,

    Can you list which pins are unused? Can you show the overall schematic?


    Unused output pins should be left open or floating.

    Unused input pins should generally be tied to GND, but this is not alwasy the case - it depends on which pin is not used, but also it depends on how the IC is being used in the application schematic.


    If you can give more details, we can give you more help.


    Thanks,
    Bernard

    Hello Bernard-san,

    Thank you for your quick reply.

    This question is a general question about this device.
    Also my customer does not have a schematic yet.

    So I will answer your reply as a general response to my customer.

    Best Regards,

    Y. Hasebe
