Write recovery time
1. A write occurs during the overlap of E low and W low.
2. Power supplies must be properly grounded and decoupled and bus contention conditions must be minimized or eliminated
3. If G goes low at the same time or after W goes low, the output will remain in a high-impedance state.
4. After W, E, or UB/LB has been brought high, the signal must remain in steady-state high for a minimum of 2 ns.
5. The minimum time between E being asserted low in one cycle to E being asserted low in a subsequent cycle is the same as
6. All write cycle timings are referenced from the last valid address to the first transition address.
7. If E goes low at the same time or after W goes low, the output will remain in a high-impedance state.
8. If E goes high at the same time or before W goes high, the output will remain in a high-impedance state.
