I agree that those specs really don't mean much, as hardly any other parameter is spec'd at those voltage. Most parameters are spec'd at +/-15V supply rails. You use it outside of those values at your own risk. | |

At a min-min :-) Vsupply cannot be less than Vcm - but Vcm min is also usually not specified - and even less so at low Vsupply. | |
