NOTES:
1. WE is high in read Cycle.
2. Device is continuously selected when CE1 = V
IL
and CE2 = V
IH
.
3. Address valid prior to or coincident with CE1 transition low and CE2 transition high.
4. OE = V
IL
.
5. Transition is measured
±
500mV from steady state with CL = 30pF as shown in Figure 1B.
The parameter is guaranteed but not 100% tested.
