NOTES:
9. Slow memory mode timing.
10. Fast memory or DMA mode of operation, except the first conversion which is equal to t
CONV
.
11. Maximum specification to prevent multiple triggering with WR.
12. All input drive signals are specified with t
r
= t
f
20ns and shall swing from V
IL
-0.4V to V
IH
+0.4V for all timing specifications. A signal is
considered to change state as it crosses a 1.4V threshold (except t
RD
and t
RX
).
13. t
r
and t
f
load is C
L
= 100pF (including stray capacitance) to DG and is measured from the 10 - 90% point.
14. t
RD
is the time required for the data output level to change by 10% in response to RD crossing a voltage level of 1.4V. High-Z to V
OH
is
measured with R
L
= 2.5k
and C
L
= 100pF (including stray) to DG. High-Z to V
OL
is measured with R
L
= 2.5k
to V+ and C
L
= 100pF
(including stray) to DG.
15. t
RX
is the time required for the data output level to change by 10% in response to RD crossing a voltage level of 1.4V. V
OH
to High-Z is
measured with R
L
= 2.5k
and C
L
= 10pF (including stray) to DG. V
OL
to High-Z is measured with R
L

to V+ and C
L
