1. tHZ1,2 and tOHZ are defined as the outputs achieve the open circuit conditions and are not referanced to output voltage levels.
2. At any given temperature and voltage condition, tHZ1,2(Max.) is less than tLZ1,2(Min.) both for a given device and from device to
device interconnection.

NOTES (WRITE CYCLE)
1. A write occurs during the overlap(tWP) of low CS1, a high CS2 and low WE. A write begins at the latest
transition among CS1 goes low, CS2 goes high and WE goes low. A write ends at the earliest transition
among CS1 goes high, CS2 goes low and WE goes high. The tWP is measured from the beginning of write
to the end of write.
2. tCW1 is measured from the CS1 going low or CS2 going high to end of write.
3. tAS is measured from the address valid to the beginning of write.
4. tWR is measured from the end or write to the address change. tWR applied in case a write ends as CS1 or WE
going high or CS2 going low.
