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 a 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
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 later than the WE low transition in write cycle 1, the output
buffers remain in a high impedance state during this period.
