1. VO = 1.4V, RS = 0Ω, 5V < VCC+ < 30V, 0V < Vic < VCC+ - 1.5V
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 no loading charge
change exists on the input lines

can be detected as this type of capacitance increases at higher frequences.
