NOTES:
1. A write occurs when CWE low.
2. If COE goes low coincident with or after CWE goes low, the output will remain in a high impedance state.
3. All timings are referenced from the last valid address to the first address transition.
4. If COE ≥ 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.
