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 con-
tention 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.
