TEST LEVEL CODES
All electrical characteristics are subject to the
following conditions:
All parameters having min/max specifications
are guaranteed. The Test Level column indi-
cates the specific device testing actually per-
formed during production and Quality Assur-
ance inspection. Any blank section in the data
column indicates that the specification is not
tested at the specified condition.
LEVEL
TEST PROCEDURE
I
100% production tested at the specified temperature.
100% production tested at T
A
= +25
°
C, and sample tested at the
specified temperatures.
QA sample tested only at the specified temperatures.
Parameter is guaranteed (but not tested) by design and characteri-
zation data.
Parameter is a typical value for information purposes only.
100% production tested at T

TIMING INFORMATION
The timing diagram for the comparator is shown in figure
1. If LE is high and LE low in the SPT9689, the comparator
tracks the input difference voltage. When LE is driven low
and LE high, the comparator outputs are latched into their
existing logic states.
The leading edge of the input signal (which consists of a
20 mV overdrive voltage) changes the comparator output
after a time of t
pdL
or t
pdH
(Q or Q). The input signal must
be maintained for a time t
S
(set-up time) before the LE fall-
ing edge and LE rising edge and held for time t
H
after the
falling edge for the comparator to accept data. After t
H
, the
output ignores the input status until the latch is strobed
again. A minimum latch pulse width of t
pL
is needed for
strobe operation, and the output transitions occur after a
time of t
pLOH
or t
pLOL
.
The set-up and hold times are a measure of the time
required for an input signal to propagate through the first
stage of the comparator to reach the latching circuitry.
Input signals occurring before t
S
will be detected and held;
those occurring after t
H
will not be detected. Changes
between t
S
and t
H
may not be detected.
