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 cir-

cuit. For proper operation, Vin and

Vout should be constrained to the

range GND v (Vin or Vout) v 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.

ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the

Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect

device reliability.

* Absolute maximum continuous ratings are those values beyond which damage to the device may occur. Exposure to these conditions or

conditions beyond those indicated may adversely affect device reliability. Functional operation under absolute−maximum−rated conditions is not

implied.
