ELECTRICAL SPECIFICATIONS
This section contains the electrical specifications for MC68HC05SR3.
11.1
Maximum Ratings
This device contains circuitry to protect the inputs against damage due to high static voltages or
electric fields. However, it is advised that normal precautions should be taken to avoid application
of any voltage higher than the maximum rated voltages to this high impedance circuit. For proper
operation
it
is
recommended
that
Vin
and
Vout
be
constrained
to
the
range
VSS≤(Vin or Vout)≤VDD. Reliability of operation is enhanced if unused inputs are connected to an
appropriate logic voltage level (e.g. either VSS or VDD).
