1. VO = 1.4 V, RS = 0 Ω, 5 V < VCC+ < 30 V, 0 V < Vic < VCC+ - 1.5 V.

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 there is no change in the loading charge 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 0.3 V.

The upper end of the common-mode voltage range is VCC+ –1.5 V, but either or both inputs can go to +32 V without

damage.

4. Due to the proximity of external components, ensure that the stray capacitance does not cause coupling between these

external parts. This can typically be detected at higher frequencies because this type of capacitance increases.
