Notes: 1. WE is high for Read Cycle.

2. Device is continuously enabled CE1 = VIL and CE2 = VIH.

3. Address valid prior to or coincident with CE1 transition low.

4. OE = VIL.

5. Transition is measured ±500mV from steady state. This parameter is sampled and not 100% tested.

6. CE2 is high.

7. CE1 is low.

8. Address valid prior to or coincident with CE2 transition high.
