NOTES:
1
W is high for read cycle.
2
Due to product sensitivities to noise, power supplies must be properly grounded and
decoupled, and bus contention conditions must be minimized or eliminated during read and
write cycles.
3
Addresses valid before or at the same time E goes low.
4
This parameter is sampled and not 100% tested.
5
Transition is measured
±200 mV from steady-state voltage.
