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.

NOTES:
1. Reference AC Operating Conditions and Characteristics for input and timing (VIH/VIL, tr/tf, pulse level 0 to 3 V, VIH = 3 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.
