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. If G goes low coincident with or after W goes low, the output will remain in a high–impedance state.
4. All timings are referenced from the last valid address to the first transitioning address.
5. If E goes low coincident with or after W goes low, the output will remain in a high–impedance state.
6. If E goes high coincident with or before W goes high, the output will remain in a high–impedance state.
