Can a ADuM1250 be used to isolate a  5V GPIO?

    Hi,
    

    Because the GPIO can use S/W programming input or output,
    so need support bidirectional isolator.
    Can a ADuM1250 be used to isolator a digital interface 5V GPIO?
    or ADuM1250 support I2C interface only?
    

    And ADuM1250 side2 output current driving is 100mA,right?

      Hi,
      

      The ADuM1250 is not constrained only to I2C applications.
      

      It can be powered from 5V. But the ADuM1250 is an open collector output, so a pull up will be required to produce a logic high state. The Side2 outputs can sink up to 30mA while meeting the logic levels specified the datasheet. (See table 1 for detailed specs)
      

      Regards,
      

      Jason
