TCA6424A: 3.3V in I/O port and 1.8V I2C SDA/SCL application

Part Number: TCA6424A

Hello expert,

May we know if customer can apply the pullup voltage 3.3V at port side and use I2C as 1.8V level? I checked the feature has description for it but I would like to know if there is any side effect for it. Thanks a lot!

Best regards,
