t
CHZ,
t
OHZ,
t
WHZ
and
t
BHZ
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
t
LZ
min both for a given device and
form device to device.
4. A write occurs during the overlap of a low CS1#, a high CS2, a low WE# and a low LB# or a low UB#.
A write begins at the latest transition among CS1# going low, CS2 going high, WE# going low and LB#
going low or UB# going low .
A write ends at the earliest transition among CS1# going high, CS2 going low, 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 CS1# going low or CS2 going high to end of write.
6.
t
AS
is measured the address valid to the beginning of write.
7.
t
WR
is measured from the earliest of CS1# or WE# going high or CS2 going low to the end of write cycle.
