NOTES:
1.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 Descriptions section.
2.ESD data available upon request.
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 volt-
ages 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.
