NOTE: Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are

exceeded. Functional operation should be restricted to RECOMMENDED

OPERATING CONDITIONS. Exposure to higher than recommended voltages for

extended periods of time could affect device reliability.

NOTES:

1. Reference AC Operating Conditions and Characteristics for input and timing (VIH/VIL, tr/tf, pulse level 0 to 3.0 V, VIH = 3.0 V).

2. All addresses transition simultaneously low (LSB) and then high (MSB).

3. Data states are all zero.

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 appli-

cation of any voltage higher than maximum

rated voltages to this high–impedance circuit.

This BiCMOS 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.
