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

tional operation should be restricted to the limits in the Electrical Characteristics tables or

Pin Descriptions section.

This device contains protection circuitry to

guard against damage due to high static

voltages or electric fields. However, precau-

tions 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.
