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.

The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V. The
upper end of the common-mode voltage range is VCC
+ -1.5V, but either or both inputs can go to +30V without damage.

5.
Positive excursions of 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 state. The low input voltage state must not be less than -
0.3V (or 0.3V bellow the negative power supply, if used).
