NOTES:
1. Transition is measured 0mV from Low or High-impedance voltage with Output Test Load (Figure 2).
2. This parameter is guaranteed by device characterazation, but is not production tested.
3. To access RAM, CE = VIL, UB or LB = VIL, and SEM = VIH. To access semephore, CE = VIH or UB & LB = VIH, and SEM = VIL.
4. 'X' in part number indicates power rating (S or L).
5. Industrial temperature: for other speeds, packages and powers contact your sales office.
