(1)

The voltage at either input should not be allowed to go negative by more than 0.3 V otherwise output may be incorrect and excessive

input current can flow. The upper end of the common-mode voltage range is limited by VCC – 2V. However only one input needs to be

in the valid common mode range, the other input can go up the maximum VCC level and the comparator provides a proper output state.

Either or both inputs can go to maximum VCC level without damage.

(2)

This parameter is ensured by design and/or characterization and is not tested in production.
