1. Operation above the absolute maximum rating may cause device failure. Operation at the absolute maximum ratings, for extended periods, may

reduce device reliability. 2. Measured in plastic DIP package, results in die form are dependent on die attach and assembly method.

3. This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be taken

to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, VIN and VOUT should be

constrained to the range GND ≤ (VIN or VOUT) ≤ VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC).

Unused outputs must be left open.
