NOTES:
1. Transition is measured 0mV from Low or High-impedance voltage with Output Test Load (Figure 2). This parameter is guaranteed by device characterization
but is not production tested.
2. PLCC package only.
3. For Master/Slave combination, tWC = tBAA + tWP, since R/W = VIL must occur after tBAA.
4. If OE is LOW during a R/W controlled write cycle, the write pulse width must be the larger of tWP or (tWZ + tDW) to allow the I/O drivers to turn off data to be placed on the
bus for the required tDW. If OE is High during a R/W controlled write cycle, this requirement does not apply and the write pulse can be as short as the specified tWP.
5. 'X' in part numbers indicates power rating (SA or LA).
6. Industrial temperature: for specific speeds, packages and powers contact your sales office.
