Note:

For the RGY package, the exposed center thermal pad must be connected to ground.

A.

Pull up resistors are not required on both sides for Logic I/O.

B.

If pull up or pull down 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 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).

D.

If pull up resistors are needed, please refer to the TXS0108 or contact TI.

E.

For detailed information, please refer to application note SCEA043.
