The TXB does not work with open-drain signals like I²C. Use the TXS0102 instead.

For unidirectional signals, a unidirectional translator like the TXU0104/TXU0204/TXU0304 would be a better choice.

Hi,

In addition to Clemens' suggestions, the customer may also refer to Voltage Translation Quick Reference for part selection depending on interface of signals.

Regards,

Jack
