are exceeded. Functional operation should be restricted to the OPERATING 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 advised that normal precautions be taken to avoid application of any voltage higher than maximum 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.
