TXB0104: buffering TXRX signal issue

Part Number: TXB0104
Other Parts Discussed in Thread: SN74AHC245

Tool/software:

I use TXB0104 as a buffer for amplifying signals form TFP2 programator. Power supplied Vcca=Vccb=3V3.
For some reason TXRX signal HI level from TFP2 side is being reduced from 3V3 to 1V by the TXB0104 translator, and it is low output after the translator (so it is no translation of the signal).
OE pin is attached to the Vcc directly. Do have somebody any ideas why its reducing and not giving the output signal?


P.S. TXRX is bi-directional signal
