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
voltages or electric fields; however, it is ad-
vised that precautions be taken to avoid
application of voltage higher than maximum
rated voltages to this high–impedance circuit.
For proper operation it is recommended that
Vin and Vout 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).
