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. All timings are 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 state.

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