2. 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.
3. 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 V
CC
+
–1.5V, but either or both inputs can go to
+32V without damage.
4. 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
frequencies.
