N.C. − No internal connection B. For RGY, if the exposed center pad is used, it must only be connected as a secondary ground or left electrically open. C. Pullup resistors are not required on both sides for Logic I/O. D. If pull up or pull down resistors are needed, the resistor value must be over 50 k Ω. E. 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). F. If pullup resistors are needed, please refer to the TXS0104 or contact TI. G. For detailed information, please refer to application note SCEA043.
