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 CEU or CEL and WE . t WP is measured from the latter of CEU ,
CEL or WE going low to the earlier of CEU , CEL or WE going high.
4) t DS is measured from the earlier of CEU or CEL or WE going high.
5) These parameters are sampled with a 5pF load and are not 100% tested.
6) If the CEU or CEL low transition occurs simultaneously with or later than the WE low transition in
the output buffers remain in a high impedance state during this period.
7) If the CEU or CEL high transition occurs prior to or simultaneously with the WE high transition, the
output buffers remain in high impedance state during this period.
