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

these external parts. This typically can be detected as this type of capacitance increases at higher

frequencies.
