VALID DATA

(4)

NOTES:

1. Transition is measured 0mV from Low or High-impedance voltage with Output Test Load (Figure1).

2. This parameter is guaranteed by device characterization, but is not production tested.

3. To access RAM,

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.
