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 5pF 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.
