TXU0102: Data direction from A to B, B to A or both?

Tool/software:

Dear TI Team,

I'm using the TXU0102DCUR in our design and according to the datasheet page 1, chapter 3, this part has fixed direction data transmission from A to B or B to A depending on how OE is referenced to either supply:

-------------------------
3 Description TXU0102 is a 2-bit, dual-supply noninverting fixed direction voltage level translation device. Ax pins are referenced to VCCA logic level, OE pin can be referenced to either VCCA or VCCB logic levels, and Bx pins are referenced to VCCB logic levels. The A port is able to accept input voltages ranging from 1.1 V to 5.5 V, while the B port can also accept input voltages from 1.1 V to 5.5 V. Fixed direction data transmission can occur from A to B or B to A when OE is set to high in reference to either supply. When OE is set to low, all output pins are in the high-impedance state. See Device Functional Modes for a summary of the operation of the control logic.
-------------------------

The functional block diagram however appears to suggest that data can only flow from A to B. 

Can you kindly confirm that this part can indeed be configured for A to B or B to A as mentioned on the first page?

Regards,

Peter Roos
