If I remember correctly we tied this pin to Vcca so that the level shifter was always enabled. I think you could drive the OE line with a transistor that was pulled up to 3.3V with a resistor or if your processor has open collector outputs you would just need the pull up resistor to 3.3V. | |

The one thing that concerns me is that OE references Vcca (3.3V) and I would like to be able to control this via logic level on the 5V side. I suppose I could do this with a pull resistor and a transitor, yes? | |
