1. VO = 1.4 V, 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 as long as the output is not saturated, so there is no

change in the loading charge on the input lines.

3. 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.
