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.
3. To access RAM, CE = VIL, SEM = VIH. To access semaphore, CE = VIH and SEM = VIL. Either condition must be valid for the entire tEW time.
4. The specification for tDH must be met by the device supplying write data to the RAM under all operating conditions. Although tDH and tOW values will vary over voltage
and temperature, the actual tDH will always be smaller than the actual tOW.
5. 'X' in part number indicates power rating (S or L).
