NOTES:
1. Transition is measured ±200mV from Low- or High-impedance voltage with Output Test Load (Figure 2).
2. This parameter is guaranteed by device characterization, but is 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).
5. Industrial temperature: for other speeds, packages and powers contact your sales office.
