This device contains protection circuitry to
guard against damage due to high static volt-
ages or electric fields. However, precautions
must be taken to avoid applications of any volt-
age higher than maximum rated voltages to
this high–impedance circuit. For proper opera-
tion, Vin and Vout should be constrained to the
range GND
≤
(Vin or Vout)
≤
VDD.
Unused inputs must always be tied to an
appropriate logic voltage level (e.g., either
GND or VDD). Unused outputs must be left
open.
