Notes: 1. Transition is measured
±
200 mV from steady voltage with Load (B). This parameter is sampled
and not 100% tested.
2. If the
CS
or
LB
or
UB
low transition occurs simultaneously with the
WE
low transition or after the
WE
transition, output remains a high impedance state.
3.
WE
and/or
CS
must be high during address transition time.
4. If
CS
,
OE
,
LB
and
UB
are low during this period, I/O pins are in the output state. Then the data
input signals of opposite phase to the outputs must not be applied to them.
5. t
AS
is measured from the latest address transition to the latest of
CS
,
WE
,
LB
or
UB
going low.
6. t
WR
is measured from the earliest of
CS
,
WE
,
LB
or
UB
going high to the first address transition.
7. A write occurs during the overlap of low
CS
, low
WE
and low
LB
or low
UB
.
8. t
CW
is measured from the later of
CS
going low to the end of write.
9. t
LBW
is measured from the later of
LB
going low to the end of write.
10.t
UBW
is measured from the later of
UB
going low to the end of write.
