When configure A as output, TXB0106 can work well. But configure A as input, TXB0106 can't work . A and B both pull down. Could you please help check it ? Thanks.

Hello Haiwen,
What is the capacitive load on A side and B side? Is B side driven across longer cables/ PCB traces? Note that the TXB is sensitive to heavy loads due to its weak drive strength and one shot circuitry. Are you able to provide scope-shots of the functioning/ non-functioning waveforms as well?
