Hi~

Can you please help me review this schematic and peripheral devices' parameters? According to my understanding, this schematic is out of problem~

If you have any other problems or concern, please let me know~ Thanks a lot!

Add some understanding:

1. The pull-up resistor is selected too small, as the datasheet shows, the pull-up resistor should be set larger than 50kOhm.

This schematic does not show any peripheral devices. The TXB datasheet lists the constraints (drive strength, capacitive load); I do not know if this circuit conforms to them.

For unidirectional translation, a unidirectional translator like the TXU0104 would be much more robust.
