Notes: 1. t
CHZ, tOHZ, t WHZ and tBHZ are defined as the time at which the outputs achieve the open circuit
conditions and are not referred to output voltage levels.
2. This parameter is sampled and not 100% tested.
3. At any given temperature and voltage condition, t
HZ max is less than tLZ min both for a given device
and from device to device.
4. A write occures during the overlap of a low
CS, a low WE and a low LB or a low UB. A write begins
at the latest transition among
CS going low, WE going low and LB going low or UB going low. A
write ends at the earliest transition among
CS going high, WE going high and LB going high or UB
going high. t
WP is measured from the beginning of write to the end of write.
5. t
CW is measured from the later of CS going low to the end of write.
6. t
AS is measured from the address valid to the beginning of write.
7. t
WR is measured from the earliest of CS or WE going high to the end of write cycle.
