Um, you are aware that that is a CURRENT FEEDBACK opamp?
You cannot use that part as a voltage comparator in the way you seem to be attempting, because the inverting input is a low impedance (few tens of ohms per the datasheet) not high Z like a voltage mode opamp would be.
There is a trap in using opamps as comparators anyway in that many of them have an internal back to back diode pair across the inputs, if you want a comparator, use a comparator, there is a reason they exist.
