This device contains protection circuitry to
guard against damage due to high static volt-
ages or electric fields. However, precautions
must be taken to avoid applications of any volt-
age higher than maximum rated voltages to this
high–impedance circuit. For proper operation,
Vin and Vout should be constrained to the range
VSS ≤ (Vin or Vout) ≤ VDD.
Unused inputs must always be tied to an ap-
propriate logic voltage level (e.g., either VSS or
VDD). Unused outputs must be left open.
