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
against damage due to high static voltages
or electric fields; however, it is advised that
normal precautions be taken to avoid appli-
cation of any voltage higher than maximum
rated voltages to this high–impedance
circuit.
This CMOS memory circuit has been de-
signed to meet the dc and ac specifications
shown in the tables, after thermal equi-
librium has been established. The circuit is
assumed to be in a test socket or mounted
on a printed circuit board with at least 300
LFPM of transverse air flow being
maintained.
