A.
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.
Pull up 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 kΩ.
E.
50 kΩ is a safe recommended value, if the customer 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).
F.
If pull up resistors are needed, please refer to the TXS0104 or contact TI.
G.
For detailed information, please refer to application note SCEA043.
