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
v v 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.

affect device reliability. Functional operation under absolute–maximum–rated conditions is not
implied.
