    The electrical characteristics shows that this device has Schmitt-trigger inputs, which implies that there is no limit on the rise/fall time.

    Hi Haiwen, 

    Thank you for your question.

    As Clemens stated, There is no limit on the rise and fall time. There is no restriction on the input signal rise time to ISO7721 input pins. The signal rise/fall time can be as fast or slow as it can be, there is no upper or lower limit.

    Regards,
    Aaditya Vittal

    P.S. Thanks Clemens!
