The direction of the input current is out of the IC. This current is essentially constant, independent of the state of the output, so no loading charge

change exists on the 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 +32V without damage.

Due to the proximity of external components insure that coupling is not originating via stray capacitance between these external parts. This typically

can be detected as this type of capacitance increases at higher frequences.
