ic < VCC

+ - 1.5V.

The direction of the input current is out of the IC. This current is essentially constant, independent of the

state of the output, so there is no change in the loading charge 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, ensure that stray capacitancedoes not cause coupling

between these external parts. Typically, this can be detected because this type of capacitance increases at

higher frequencies.
