NOTES:
1. Transition is measured 0mV fromLow- or High-impedance voltage with load (Figures 1 and 2).
2. This parameter is guaranteed by device characterization but not tested.
3. To access RAM
CE
= V
IL
and
SEM
= V
IH
. To access semaphore,
CE
= V
IH
and
SEM
= V
IL
.
4. 'X' in part numbers indicates power rating (S or L).
