NOTES:
1. WE\ is high in read cycle.
2. Device is continuously selected when CE\ = VIL
3. Address valid prior to or coincident with CE\ transition low.
4. OE\ = VIL.
5. Transition is measured ±500mV from steady state with CL=5pF as shown in Figure 1B. The
parameter is guaranteed but not 100% tested.
