NOTES:
1. Transition is measured 0mV from Low- 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 = VIL and SEM = VIH. To access semaphore, CE = VIH and SEM = VIL.
4. 'X' in part numbers indicates power rating (S or L).
