)
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 that 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 that except for pin 8,
V

and V
out
be constrained to the range V
