NOTES(READ CYCLE)

1. WE is high for read cycle.

2. All read cycle timing is referenced from the last valid address to the first transition address.

device.

5. Transition is measured

±200mV from steady state voltage with Load(B). This parameter is sampled and not 100% tested.

7. Address valid prior to coincident with CS transition low.

8. For common I/O applications, minimization or elimination of bus contention conditions is necessary during read and write cycle.
