1. t HZ 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, t HZ(Max.) is less than t LZ(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
when CS1 goes high, CS2 goes hagh and WE goes high. The t WP is measured from the beginning of write
to the end of write.
2. t CW is measured from the CS1 going low to end of write.
3. t A S is measured from the address valid to the beginning of write.
4. t WR is measured from the end or write to the address change. tWR applied in case a write ends as CS1 or WE
going high.
