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. 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.
