This device contains protection circuitry to

guard against damage due to high static

voltages or electric fields. However, pre-

cautions must be taken to avoid applications

of any voltage 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

appropriate logic voltage level (e.g., either

VSS or VDD). Unused outputs must be left

open.
