1.
2. The direction of the input current is out of the IC. This current is essentially constant, independent of the state of the output,
3. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3 V.
4. Due to the proximity of external components, ensure that the stray capacitance does not cause coupling between these
