* 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 Descrip-
tion section.
This device contains circuitry to protect the inputs
against damage due to high static voltages or elec-
tric fields; however, it is advised that normal precau-
tions to be taken to avoid application of any voltage
higher than maximum rated voltages to this high
impedance circuit. For proper operation it is recom-
mended that Vin and Vout be constrained to the
range VSS < or = (Vin or Vout) < or = VDD. Reliability
of operation is enhanced if unused input are con-
nected to an appropriate logic voltage level (e.g.,
either VSS or VDD). Unused outputs must be left
open. This device may be light sensitive. Caution
should be taken to avoid exposure of this device to
any light source during normal operation. This
device is not radiation protected.
