Differential input voltage (2)

2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.

Input voltage (3)

3. Excursions of input voltages may exceed the power supply level. As long as the common mode voltage

[Vicm=(Vin+ + Vin-)/2] remains within the specified range, the comparator will provide a stable output state.

However, the maximum current through the ESD diodes (IF) of the input stage must strictly be observed.
