NOTES:

1. W is high for read cycle.

2. Product sensitivities to noise require proper grounding and decoupling of power supplies as well as minimization or elimination of bus

contention conditions during read and write cycles.

3. E1, E2, and E3 are represented by E in this data sheet. E2 is of opposite polarity to E1 and E3.

4. All read cycle timings are referenced from the last valid address to the first transitioning address.

5. Addresses valid prior to or coincident with E going low.

6. At any given voltage and temperature, tEHQZ max t tELQX min, and tGHQZ max t tGLQX min, both for a given device and from device

to device.

7. Transition is measured

± 200 mV from steady–state voltage.

8. This parameter is sampled and not 100% tested.

9. Device is continuously selected (E

≤ VIL, G ≤ VIL).
