Hi Marugavel,
I edited your post to directly include the image you provided.

The TXB0104 is not an isolation device and cannot be used as shown. All internal grounds are directly connected together.

The TXB0104 has a single ground pin, and in any case uses a common ground for both sides.

When you want isolation, you must use an isolator.
