AC Characteristics
Notes:
1. Maximum value is applicable if CE1# is kept at Low without any address change. If the relaxation is needed by system
2. Minimum value must be equal or greater than the sum of write pulse (t
3. Write pulse is defined from High to Low transition of CE1#, WE#, or LB#/UB#, whichever occurs last.
4. Applicable for byte mask only. Byte mask setup time is defined to the High to Low transition of CE1# or WE# whichever
5. Applicable for byte mask only. Byte mask hold time is defined from the Low to High transition of CE1# or WE# whichever
6. Write recovery is defined from Low to High transition of CE1#, WE#, or LB#/UB#, whichever occurs first.
7. t
8. If OE# is Low after minimum t
9. If OE# is Low after new address input, read cycle is initiated. In other word, OE# must be brought to High at the same time
