Note 4: 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 change exists on the input lines.
Note 5: The input common-mode voltage of either input signal voltage should not be allowed to go negatively by
more than 0.3V (at 25^oC). The upper end of the common-mode voltage range is V_CC - 1.5V (at 25^oC), but either
or both inputs can go to +18V without damages, independent of the magnitude of the V_CC.
Note 6: Due to proximity of external components, insure that coupling is not originating via stray capacitors
between these external parts. This typically can be detected as this type of capacitance increases at higher fre-
quencies.
