Functional operating conditions are given in DC Electrical Specifications. Absolute Maximum
Ratings are stress ratings only, and functional operation at the maxima is not guaranteed. Stress
beyond those listed may affect device reliability or cause permanent damage to the device.
This device contains circuitry protecting against damage due to high static voltage or electrical
fields; however, it is advised that normal precautions be taken to avoid application of any voltages
higher than maximum-rated voltages to this high-impedance circuit. Reliability of operation is
enhanced if unused inputs are tied to an appropriate logic voltage level (e.g., either V
Input must be current limited to the I
current-limiting resistor, calculate resistance values for positive and negative clamp voltages, then
use the larger of the two values.
All functional non-supply pins are internally clamped to V

maintain regulation within operating V
current conditions.
The use of this device in one- or two-layer board designs is not recommended due to the
limited thermal conductance provided by those boards.
