Notes:
1. The internal Write time is defined by the overlap of
CE
= LOW,
UB
and/or
LB
= LOW, and
WE
= LOW. All signals must be
in valid states to initiate a Write, but any can be deasserted to terminate the Write. The
t
SA
,
t
HA
,
t
SD
, and
t
HD
timing is
referenced to the rising or falling edge of the signal that terminates the Write.
2. Tested with
OE
HIGH for a minimum of 4 ns before
WE
= LOW to place the I/O in a HIGH-Z state.
3.
WE
may be held LOW across many address cycles and the
LB
,
UB
pins can be used to control the Write function.
