All writes occur during the overlap of E low and W low. Power supplies must be properly grounded and decoupled and bus
contention conditions must be minimized or eliminated during read and write cycles. If G goes low at the same time or after
W goes low, the output will remain in a high impedance state. After W or E has been brought high, the signal must remain in
steady-state high for a minimum of 2 ns. The minimum time between E being asserted low in one cycle to E being asserted
low in a subsequent cycle is the same as the minimum cycle time allowed for the device.
All write cycle timings are referenced from the last valid address to the first transition address.

If E goes low at the same time or after W goes low, the output will remain in a high-impedance state. If E goes high at the
same time or before W goes high, the output will remain in a high-impedance state.
