Hi, I have a design transfering 8 bit parallel data between two I/O ports of MCUs. The data path needs to be able of withstanding 30+Vdc, therefore I need isolation at both TX and RX sides. I plan to use two optocouplers for each data line, one optocoupler's output connects to another optocoupler's input, i.e. the 2nd optocoupler's diode Anode will be one end of the data path, the 1st optocoupler emitter will be another end of the data path.
Is there any potential problem or better solution? I appreciate your help!
