18.3.5 Pullup or Pulldown Resistors on I/O Lines

The device is designed to support high-drive applications with either a lumped capacitive load of up to 100pF or a signal trace length of up to 20 inches with a 50pF load. The output drivers of the TXB0606 device have low DC drive strength. If pullup or pulldown resistors are connected externally to the data I/Os, their values must be kept higher than 20kΩ to ensure that they do not contend with the output drivers of the TXB0606 device.

For the same reason, the TXB0606 device must not be used in applications such as I2C or 1-Wire where an open-drain driver is connected on the bidirectional data I/O. For these applications, use a device from the TI TXS series of level translators.
