NOTES:

1. Timing depends on which signal is asserted last,

OE or CE.

2. Timing depends on which signal is de-asserted first,

CE or OE.

BUSY has no relation to valid output data.

1. Transition is measured

±200mV 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. To access RAM,

5. "X" in part numbers indicates power rating (S or L).
