WARNING:
Under no circumstance are negative undershoots, of any amplitude, allowed when device is in battery
backup mode.
NOTES:
1. W E is high for a Read Cycle.
2. OE = V IH or V IL . If OE = V IH during write cycle, the output buffers remain in a high-impedance state.
3. t WP is specified as the logical AND of CE and WE . t WP is measured from the latter of CE or WE
going low to the earlier of CE or WE going high.
4. t DH , t DS are measured from the earlier of CE or WE going high.
5. These parameters are sampled with a 5 pF load and are not 100% tested.
6. If the CE low transition occurs simultaneously with or latter than the WE low transition, the output
buffers remain in a high-impedance state during this period.
7. If the CE high transition occurs prior to or simultaneously with the WE high transition, the output
buffers remain in high-impedance state during this period.
