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.
