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 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 BiCMOS memory circuit has been

designed 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.
