We are using ISO1540QDRQ1 in our design.We have connected 4 INA228AQDGSRQ1 and one ADS1115IDYNR to the same I2C bus and connected to the I2C isolator on one side and the other side is connected to the microcontroller FS32K144HAT0MLHT. please let me know if this is fine. below is the schematics.The I2C bus connected to pin 6 and 7 is connected to 5 devices(address is all different for each device)

    Hello Prema, 

    Thank you for reaching out.

    The secondary side should be capable of driving 5 devices and the primary side is intended to have a direct connection to the MCU. Therefore, your schematic and application description make sense, and I do not expect any issues. 

    Best,
    Andrew
