1. L = Logic Low; H = Logic High; X = Don’t Care.
2. GX/GY must be negated during write and pass–through cycles.
3. Operation numbers 3 – 6 can be used in any combination.
4. Operation numbers 4 and 7, 3 and 8, 7 and 8 can be combined.
5. Operation number 5 can not be combined with operation number 7 or 8 because pass–through takes precedence over a read operation.
6. Operation number 6 can not be combined with operation number 7 or 8 because pass–through takes precedence over a read operation.
1. Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are
2. Power dissipation capability is dependent upon package characteristics and use
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.
