Notes: 1. All voltage is referenced to V

2. Permanent device damage may occur if absolute maximum ratings are exceeded. Functional

operation should be restricted the operation conditions. Exposure to higher voltages 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.

4. The following supply voltage application sequence is recommended: V

Remember, according to the absolute maximum ratings table, V

whatever the instantaneous value of V
