Maximum Ratings
The maximum ratings are the limits to which the device can be subjected without permanently
damaging the device.
Note: The device is not guaranteed to operate properly at the maximum ratings.

a. Voltages are measured with respect to GND.
Important: 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. Reliability of operation is enhanced if unused inputs are
connected to an appropriate logic voltage level (for example, either GND or V_DD).
