A.

See mechanical drawings for dimensions.

B.

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

C.

If pullup or pulldown resistors are needed, the resistor value must be over 50 k

Ω.

D.

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).

E.

If pull up resistors are needed, please refer to the TXS0101 or contact TI.

F.

For detailed information, please refer to application note SCEA043.
