NOTES:
1. A write occurs during the overlap of E low and W low.
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. All timings are referenced from the last valid address to the first transitioning address.
4. Transition is measured
±
500 mV from steady–state voltage with load of Figure 1b.
5. This parameter is sampled and not 100% tested.
6. At any given voltage and temperature, tWLQZ max is less than tWHQX min both for a given device and from device to device.
