.
2. Permanent device damage may occur if Absolute Maximum Ratings are exceeded. Functional
operation should be restricted the Operation Conditions. Exposure to higher than recommended
voltages for extended periods of time could affect device reliability.
3. These CMOS memory circuits have been designed to meet the DC and AC specifications shown
in the tables after thermal equilibrium has been established.
