Notes:
1. The output load is 30 pF.
2. The output load is 5 pF.
3. The t
CE
is applicable if
OE
is brought to Low before
CE
1r goes Low and is also applicable if actual value of both
or either t
ASO
or t
CLOL
is shorter than specified value.
4. Applicable only to A0 and A1 when both
CE
1r and
OE
are kept at Low for the address access.
5. Applicable if
OE
is brought to Low before
CE
1r goes Low.
6. The t
ASO
, t
CLOL
(Min) and
t
OP
(Min) are reference values when the access time is determined by t
OE
.
If the actual value of each parameter is shorter than the specified minimum value, t
OE
becomes longer by the amount
of subtracting actual value from specified minimum value.
For example, if actual t
ASO
, t
ASO
(actual) , is shorter than specified minimum value, t
ASO
(Min) , during
OE
control
access (i.e.,
CE
1r stays Low) , the t
OE
becomes t
OE
(Max) + t
ASO
(Min) - t
ASO
(actual) .
7. The t
ASO
[
ABS
] and t
OP
[
ABS
] are the absolute minimum values during
OE
control access.
8. If actual value of either t
CLOL
or t
OP
is shorter than specified minimum value, both t
OLAH
and t
OLCH
become t
RC
(Min)
- t
CLOL
(actual) or t
RC
(Min) - t
OP
(actual) .
9. Maximum value is applicable if
CE
1r is kept at Low
.
