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.

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 highimpedance 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.
