A. Pullup resistors are not recommended on TXB0102 I/O pins.
B. If pullup resistors are needed for open drain communication, please refer to the TXS0102 or contact TI.
C. If pullup or pulldown resistors are needed, the resistor value must be over 50 kΩ. See Effects of External Pullup and Pulldown Resistors on TXS and TXB Devices .
D. 50 kΩ is a safe recommended value, if the customer can accept higher Vol or lower VCCOUT, smaller pullup or pulldown resistor is allowed, the draft estimation is VOL = VCCOUT × 4.5k/(4.5k + Rpu) and VOH = VCCOUT × Rdw/(4.5k + Rdw).
