    Hi Chen,

    The TXB is suited for SPI communication as the device is auto-bidirectional in nature.
    You could also consider using the SN74AXC8T245 or the SN74AVC4T774 for this.

    In your block diagram, how is the control of each of the TXB device done? I am concerned that the TXB1 could be triggered by output of TXB2 or TXB3. The OE pin has to be controlled using the MCU.
