* 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.
