NOTE: Permanent device damage may occur If ABSOLUTE MAXIMUM RATINGS are
exceeded. Functional operation should be restricted to the OPERATING CONDI-
TIONS. Exposure to higher than recommended voltages for extended periods of
time could affect device reliability.
This device contains circuitry to protect the
inputs against damage due to high static volt-
ages or electric fields; however, it is advised
that normal precautions be taken to avoid
application of any voltage higher than maxi-
mum rated voltages to these high-impedance
circuits.
This CMOS memory circuit has been de-
signed to meet the dc and ac specifications
shown in the tables, after thermal equilibrium
has been established.
This device contains circuitry that will
ensure the output devices are in High Z at
power up.
