1.

Vo = 1.4 V, Rs = 0 Ω, 5 V < VCC

+ < 30 V, 0 < V

ic < 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 load 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 stray capacitance between these external parts does not cause

coupling. Typically, this can be detected because this type of capacitance increases at higher frequencies.
