NOTES:
1. X means Don’t Care.
2. All inputs except G must meet setup and hold times for the low–to–high transition of clock (K).
3. S represents S0 and S1. T implies S1 = L and S0 = H; F implies S1 = H or S0 = L.
4. Wait states are inserted by suspending burst.

2. For a write operation following a read operation, G must be high before the input data
required setup time and held high through the input data hold time.

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
voltages or electric fields; however, it is ad-
vised 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.
