ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ * Maximum Ratings are those values beyond which damage to the device may occur.

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.

Functional operation should be restricted to the limits in the Electrical Characteristics

tables or Pin Descriptions section.
