ADCMP380 Input Range?

What is the input range ("IN" pin) of the ADCMP380? I can't find any clear indication in the datasheet.

 

The following table on Analog's website seems to suggest the input range is 2 V to 5.5 V, but that doesn't seem to make sense based off the internals of the device.

I'd like to use this IC to detect if a low voltage signal (that is near ground) exceeds 0.5 V or not. I don't plan to use any resistor division in my circuit, so the input signal into the ADCMP380 will range from 0 V to about 1.3 V.
