Nope, the converter pulled it always low

So you tried this?
I tried this and it worked.... I have spent so many hours trying to "debug" this and actually ended up using a logic level shifter (4 input) for an earlier project.
This worked right out of the bat for me. I had earlier tired OE floating, OE pull up, OE pull down.... Just had never though of connecting OE both to 3.3V as well as GND (Via resistor).
PS: I am not using an arduino, it is being driven off an ESP8266, if that matters.

Just to add my experience with the exact same problem.
The only way I could get my circuit to work was to take the OE pin high (to 3.3v) via a 1KO resistor (and no path to ground).
and to put bypass capacitors (100 uF) from VB to ground and from VA to ground.

I had similar issues when I tried that chip and eventually just used a different IC.
