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.

Posistive 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).
