WARNING:
Under no circumstances are negative undershoots, of any amplitude, allowed when device is in the
battery backup mode.
NOTES:
1.
WEis high for a read cycle.
2.
OE= V
IH

. 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 CEand WE. t
WP
is measured from the latter of CE or CE
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 later than the WE low transition, the output
buffers remain in a high-impedance state during this period.
