NOTES:
2738 tbl 13
1. Transition is measured
±500mV from Low or High-impedance voltage with Output Test Load (Figures 2).
2. This parameter is guaranteed by device characterization but not production 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).
