NOTE: Maximum Ratings are those values beyond which damage to the device may occur.
Functional operation should be restricted to the limits in the Electrical Characteristics
tables or Pin Description section.
This device contains protection circuitry to guard
against damage due to high static voltages or
electric fields. However, precautions must be
taken to avoid applications of any voltage higher
than maximum rated voltages to this high-imped-
ance 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 appro-
priate logic voltage level (e.g., either VSS or
VDD). Unused outputs must be left open.
