    Hi Clément, Thanks for the detailed description of the issue. The value of pull ups will change the rise and fall time which affects the data rate, but it will not have any effect on the final voltage. The 1V and 2V spike difference is for the same…

    Hi Jay, Thanks for reaching out. The signals that you are measuring are behaving as expected. The ISO1644 has a diode in the design in order to have a bi-directional communication. It is a common practice in industry for isolated i2c communication. For more…
