TCA9548A-Q1 Voh information for this part is not available in the datasheet, could you please provide the information

    There is no VOH specification because this device never outputs a high signal. I²C signals are open drain, and the eight channels are connected through passive switches.

    Hey Sobin,

    Clemens is correct here- since this device supports the I2C standard which doesn't utilize any PFET drivers (solely relies on pullup resistors), then it wouldn't be correct to characterize VOH. The rise time would be based on the passive RC components surrounding the I2C bus/ device.

    Please let us know if you have any further questions.

    Regards,

    Jack
