A. The exposed center pad, if used, must be connected as a secondary ground or left electrically open.
B. Pull up resistors are not required on both sides for Logic I/O.
C. If pull up or pull down resistors are needed, the resistor value must be over 50kΩ.
D. 50kΩ is a safe recommended value, if the user can accept higher Vol or lower Voh, smaller pull up or pull down resistor is allowed, the draft estimation is VOL = VCCOUT × 4.5k ÷ (4.5k + RPU) and VOH = VCCOUT × RDW ÷ (4.5k + RDW).
E. If pull up resistors are needed, please refer to the TXS0108 (different package with TXB0106), or contact TI.
F. For detailed information, please refer to the A Guide to Voltage Translation With TXB-Type Translators application note.
