Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
3. The input common mode voltage of either input signal should not be allowed to go negative by more than 0.3 V. The upper end of the common
mode voltage range is VCC – 1.5 V, but either or both inputs can go to +30 V without damage.
4. Positive excursions of the input voltage may exceed the power supply level. As long as the other voltage remains within the common mode
range, the comparator will provide a proper output stage. The low input voltage state must not be less than 0.3 V below the negative supply
rail.
