1. tHZ and tOHZ are defined as the time at which the outputs achieve the open circuit conditions and are not referenced to output voltage
levels.
2. At any given temperature and voltage condition, tHZ(Max.) is less than tLZ(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 CS and low WE. A write begins when CS goes low and WE goes low with asserting UB
or LB for single byte operation or simultaneously asserting UB and LB for double byte operation. A write ends at the earliest transi-
tion when CS goes high and WE goes high. ThetWP is measured from the beginning of write to the end of write.
2.tCW is measured from the CS going low 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 CS or WE going high.
