Can we connect open drain inputs to ISO676x digital isolators.

Thanks in advance.

    Hello,

    Thank you for your question. Are you asking if open drain outputs can be connected to the input pins of the ISO676x digital isolators? If this is the case, yes, open drain outputs can be connected as inputs to digital isolators, but an external pull up resistor will be needed. We normally recommend a resistor value of 4.7k but anything between 1k and 10k is usually acceptable for most use cases.

    Regards,
