These devices contain circuitry
to
protect
the inputs against damage
due
to
high static voltages
or
elec-
trical fields; however,
it
is advised
that
normal precautions be taken
to
avoid application
of
any voltage
higher
than
maximum
rated
voltages
to
this high-impedance
circuit. For proper operation
it
is
recommended
that
Vin and
Vout
be constrained
to
the
range
VSSs(Vin
and
Vout)SVCC·
Reliabiity
of
operation
is
enhanced
if
unused inputs except EXT
AL
are
tied
to
an
appropriate logic voltage
level (e.g., either VSS
or
VCCl.
