4. Due to the PNP input stage the direction of the input current is out of the IC. No loading change exists on the input lines because the current is
essentially constant, independent of the state of the output.
5. The input signal voltage and the input common mode voltage should not be allowed to go negative by more than 0.3V. The positive limit of the
common mode voltage range is V+ - 1.5V, but either or both inputs can go to +32V without damage.
