    Hi Gary ,

    Functionality is the same , however, the operating conditions and the electrical characteristics will vary .
    I will move this into voltage translation forum for support .

    Hi Gary

    There are no concerns with the schematic.

    As Shreyas mentioned the functionality will remain the same. Please follow the datasheet electrical specification f or the respective 1.8V and 3.0V. The drive current is higher in the LVC part. The prop delays are much lower in the AVC part. The data rates will be different too.

    Thanks
