AC Test Conditions
Timing of Power-Up Power-Down
NOTES:
1. Timing depends on which signal is asserted last, OE, CE, LB or UB.
2. Timing depends on which signal is de-asserted first CE, OE, LB or UB.
3. t
4. Start of valid data depends on which timing becomes effective last t
5. SEM = V
6. Refer to Truth Table I - Chip Enable.
