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 ex-

tended 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 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 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.
