Hi,

The schematic looks fine. Can you clarify a few things for me?

In your post you say that VCCA and VCCB are both 3.3V but the tag for you post has '1.8V to 3.3V translation'. Are you translating from 1.8V to 3.3V or are both supplies at 3.3V?

Is the issue that you are expecting 3.3V at the output but are only seeing around 2.3V?
