NOTES:
1. Transition is measured
±
200mV from Low or High-impedance voltage with the Output Test Load (Figure 2).
2. This parameter is guaranteed by device characterization but not production tested.
3. To access RAM,
CE
= V
IL
and
SEM
= V
IH
. To access semaphore,
CE
= V
IH
and
SEM
= V
IL
. Either condition must be valid for the entire t
EW
time.
4. The specification for t
DH
must be met by the device supplying write data to the RAM under all operating conditions. Although t
DH
and t
OW
values will vary
over voltage and temperature, the actual t
DH
will always be smaller than the actual t
OW
.
5. "X" in part numbers indicates power rating (S or L).
