NOTES:
1. Transition is measured 0mV from Low or High-impedance voltage with load (Figure 2).
2. This parameter is guaranteed by device characterization, but is not production tested but not tested.
3. To access RAM, CE = V IL , SEM = V IH . To access semaphore, CE = V IH and SEM = V IL . Either condition must be valid for the entire t EW time.
4. The specification for t DH must be met by the device supplying write data to the RAM under all operating conditions. Although t DH and t OW values will vary over voltage
and temperature, the actual t DH will always be smaller than the actual t OW .
5. 'X' in part numbers indicates power rating (S or L).
