Hi team,

My customer is evaluating about using the isolator replace photo-coupler, they want to know the differences, trade-off

Do we have an application note on it?

    Hi Roger,

    The ISO1640 is a an I2C Isolator. I'm not sure what is the application of customer and what purpose does the photo-coupler serve in their schematic

    Before commenting on ISO1640 as a replacement part, we'll need little more context on the MPN of Photo Coupler and how is customer using it in their system.
