NOTES:

1. WE is high in read Cycle.

2. Device is continuously selected when CE1 = VIL and CE2= VIH.

3. Address valid prior to or coincident with CE1 transition low and/or CE2 transition high.

4. OE = VIL .

5. Transition is measured ± 500mV from steady state with CL = 5pF as shown in Figure 1B.

The parameter is guaranteed but not 100% tested.
