2. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output, so no loading charge exists on the reference of input lines.

4. Positive voltage excursions of one input may exceed the power supply level. As long as the other input voltage remains within the common-mode range, the comparator will provide an appropriate output state. The low input voltage state must not be less than -0.3V (or 0.3V below the negative power supply, if used).
