Part Number: ISO1540

Hi Sir,

ISO1540 is designed in our customer project for 3.3V I2C function. Is another part compatible to ISO1504(3.3V I2C function) and supporting to creepage >5mm?

Thanks, Ian.

    Hi Ian,

    Unfortunately, we currently do not have an isolated I2C device in a package with creepage >5mm. Do you know what working voltage is customer looking for?
    We do have an alternate way to support isolated I2C using digital isolators that support reinforced isolation and creepage upto 14mm. Please refer to the link below that describes how to achieve isolated I2C channels using digital isolators. Let me know if you have any questions, thanks.
