NOTE: Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are ex-
ceeded. Functional operation should be restricted to RECOMMENDED OPERAT-
ING CONDITIONS. Exposure to higher than recommended voltages for extended
periods of time could affect device reliability.
The devices on this module contain circuitry
to protect the inputs against damage due to
high static voltages or electric fields; however,
it is advised that normal precautions be taken
to avoid application of any voltage higher than
maximum rated voltages to these high imped-
ance circuits.
These CMOS memory circuits have been
designed to meet the dc and ac specifications
shown in the tables, after thermal equilibrium
has been established. The module 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.
