Hi experts team

In the application circuit, do we recommend to add the serial resistors between MCU and TXB0106? Like 22ohm or 30ohm.

Hi Shaofeng,

Yes, to help minimize reflections as much as possible. Dependent on the system and the system designer's tolerance for various parameters for the clearest understanding of signal integrity.

Best Regards,
