HIGH IMPEDANCE
Notes:
6.
CE
1
and
WE
are
LOW
and
CE2
is
HIGH
for
WRITE
cycle.
7. OE is LOW for this WRITE cycle to show twz and tow.
8.
If
CE
1
goes
HIGH
or
CE2
goes
LOW
simultaneously
with
WE
HIGH,
the
output
remains
in
a
high
impedance
state.
9. Write Cycle Time is measured from the last valid address to the first transitioning address.
