This current essentially is constant and independent of the state of the output, so no loading change exists on the input lines. (2) The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3 V. The upper end of the common-mode voltage range is V+ – 1.5 V, but either or both inputs can go to 32 V without damage. (3) Due to proximity of external components, ensure that coupling is not originating via the stray capacitance between these external parts. This typically can be detected, as this type of capacitive coupling increases at higher frequencies. (4) Positive excursions of input voltage may exceed the power-supply level. As long as the other input voltage remains within the common-mode range, the comparator provides a proper output state. The input voltage to the operational amplifier should not exceed the power-supply level. The input voltage state must not be less than –0.3 V (or 0.3 V below the magnitude of the negative power supply, if used) on either amplifier.
