This device contains circuitry to protect the
inputs against damage due to high static volt-
ages or electric fields. However, it is advised
that normal precautions be taken to avoid
applications of any voltage higher than maxi-
mum rated voltages to this high impedance
circuit. For proper operation, it is recommended
that Vin and Vout be constrained to the range
VSS ≤ (Vin or Vout) ≤ VDD.
Reliability of operation is enhanced if unused
logic inputs are tied to an appropriate logic volt-
age level (e.g., either VSS or VDD).
