    Hey Jiawei,

    I recommend they use the TXU0304-Q1 device for this. It shares the same pinout, but the channels are fixed direction. TXS does not work well with heavy capacitive loads and should not be used with pull-downs. TXU will have strong buffered outputs and schmitt-trigger inputs making it ideal for this. Its OE pin can also be operated in the same way with one device being enabled at a time.
