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 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).
