NOTES:
3026 tbl 10
1. Transition is measured 0mV 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. 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.
4. 'X' in part numbers indicates power rating (S or L).
5. For Master/Slave combination, tWC = tBAA + tWP, since R/W = VIL must occur after tBAA.
