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. If G goes low coincident with or after W goes low, the output will remain in a high–impedance state.
4. All write cycle timings are referenced from the last valid address to the first transitioning address.
5. This parameter is sampled and not 100% tested.
6. Transition is measured
±
200 mV from steady–state voltage.
7. At any given voltage and temperature, tWLQZ max < tWHQX min both for a given device and from device to device.
