WARNING:
Under no circumstance are negative undershoots, of any amplitude, allowed when device is in battery backup mode.
NOTES:
1. WE 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
DS
is 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.
8. If WE is low or the WE low transition occurs prior to or simultaneously with the CE low transition, the output buffers
remain in a high impedance state during this period.
