1. Maximum Ratings are those values beyond which damage to the device may occur. This device contains circuitry to protect the inputs against
damage due to high static voltages or electric fields; however, it is advised normal precautions be taken to avoid application of any voltage
higher than maximum rated voltages to this high impedance circuit. For proper operation it is recommended VIN and VOUT be constrained to
the range VSS ≤ (VIN or VOUT) ≤ VDD.
