TXS0108E used in multiple slave SPI

I try to use TXS0108E in multiple slave SPI.
I want to convert 5V to 3.3V for TFT and provided 3.3V (from Arduino Mega Board) to VccA and 5V (from Arduino Mega Board) to VccB and Ground of TXS0108E to ground of Arduino Mega Board.
But I have found that pins from A1 to A8 gets 3.3V and pins from B1 to B8 gets 5V.
I have tried OE pin to ground through 10 K resistor but still the situation of all pins are like above.
I have tried OE pin to 3.3 but still there is no change in pin voltage.
I have attached TXS0108E photo for reference.

Why this happen in TXS0108E? Any comments.

See the functional block diagram on page 17 and you'll understand why this is the case. Both sides have pull-ups to VccA rsp. VccB. This is exactly what you would expect from a bidirectional level converter.

What did you expect?
