NOTES:
1. A write occurs during the overlap of E low and W low.
2. If E goes low coincident with or after W goes low, the output will remain in a high impedance state.
3. All timings are referenced from the last valid address to the first transitioning address.
4. If E ≥ VIH, the output will remain in a high impedance state.
5. At any given voltage and temperature, tWLQZ (max) is less than tWHQX (min), both for a given device and from device to device.
6. Transition is measured ±500 mV from steady–state voltage with load of Figure 1B.
7. This parameter is sampled and not 100% tested.
