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.
