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. All write cycle timing is referenced from the last valid address to the first transitioning address.

4. If E goes low coincident with or after W goes low, the output will remain in a high impedance condition.

5. If E goes high coincident with or before W goes high, the output will remain in a high impedance condition.
