* Maximum Ratings are those values beyond which damage to the device may occur. Func-
tional operation should be restricted to the Operation Ranges below..
This device contains protection circuitry to
guard against damage due to high static
voltages or electric fields. However, pre-
cautions 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.
Unused inputs must always be tied to an
appropriate logic voltage level (e.g., either
VSS or VDD). Unused outputs must be left
open.
