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 V
range V
of operation is enhanced if unused input are con-
nected to an appropriate logic voltage level (e.g.,

should be taken to avoid exposure of this device to
any light source during normal operation. This
device is not radiation protected.
