A. Pullup resistors are not required on both sides for Logic I/O. B. If pullup or pulldown resistors are needed, the resistor value must be over 50 k Ω. C. 50 k Ω is a safe recommended value, if the customer can accept higher VOL or lower VOH, smaller pullup or pulldown resistor is allowed, the draft estimation is VOL = VCCOUT × 4.5 k/(4.5 k + RPU) and VOH = VCCOUT × RDW/(4.5 k + RDW). D. If pullup resistors are needed, please refer to the TXS0108 or contact TI. E. For detailed information, please refer to application note SCEA043. Pin Functions PIN I/O(1) FUNCTION NAME PW, RGY NO.
