NOTE: Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are
exceeded. Functional operation should be restricted to RECOMMENDED OPER-
ATING CONDITIONS. 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
voltages or electric fields; however, it is ad-
vised 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. The circuit is in a test
socket or mounted on a printed circuit board
and transverse air flow of at least 500 linear
feet per minute is maintained.
