Description
The 6N137, HCPL-26XX/06XX/
4661, HCNW137/26X1 are
optically coupled gates that
combine a GaAsP light emitting
diode and an integrated high gain
photo detector. An enable input
allows the detector to be strobed.
The output of the detector IC is
A 0.1
µ
F bypass capacitor must be connected between pins 5 and 8.

an open collector Schottky-
clamped transistor. The internal
shield provides a guaranteed
common mode transient
immunity specification of 5,000
V/µs for the HCPL-X601/X631
and HCNW2601, and 10,000 V/µs
for the HCPL-X611/X661 and
HCNW2611.
This unique design provides
maximum ac and dc circuit
isolation while achieving TTL
compatibility. The optocoupler ac
and dc operational parameters
are guaranteed from -40°C to
+85°C allowing troublefree
system performance.
The 6N137, HCPL-26XX, HCPL-
06XX, HCPL-4661, HCNW137,
and HCNW26X1 are suitable for
high speed logic interfacing,
input/output buffering, as line
receivers in environments that
conventional line receivers
cannot tolerate and are recom-
mended for use in extremely high
ground or induced noise
environments.

4. Derate linearly above 80°C free-air temperature at a rate of 2.7 mW/°C for the SOIC-8 package.
5. Bypassing of the power supply line is required, with a 0.1 µF ceramic disc capacitor adjacent to each optocoupler as illustrated in
Figure 17. Total lead length between both ends of the capacitor and the isolator pins should not exceed 20 mm.

9. The JEDEC registration for the 6N137 specifies a maximum IEL of –2.0 mA. HP guarantees a maximum IEL of -1.6 mA.
10. The tPLH propagation delay is measured from the 3.75 mA point on the falling edge of the input pulse to the 1.5 V point on the
rising edge of the output pulse.
11. The tPHL propagation delay is measured from the 3.75 mA point on the rising edge of the input pulse to the 1.5 V point on the
falling edge of the output pulse.
12. tPSK is equal to the worst case difference in tPHL and/or tPLH that will be seen between units at any given temperature and specified
test conditions.
13. See application section titled “Propagation Delay, Pulse-Width Distortion and Propagation Delay Skew” for more information.
14. The tELH enable propagation delay is measured from the 1.5 V point on the falling edge of the enable input pulse to the 1.5 V
point on the rising edge of the output pulse.
15. The tEHL enable propagation delay is measured from the 1.5 V point on the rising edge of the enable input pulse to the 1.5 V point
on the falling edge of the output pulse.
16. CMH is the maximum tolerable rate of rise of the common mode voltage to assure that the output will remain in a high logic state
(i.e., VO > 2.0 V).

21. In accordance with UL1577, each optocoupler is proof tested by applying an insulation test voltage ≥ 3000 V rms for one second
(leakage detection current limit, II-O ≤ 5 µA). This test is performed before the 100% production test for partial discharge

Propagation Delay, Pulse-
Width Distortion and
Propagation Delay Skew
Propagation delay is a figure of
merit which describes how
quickly a logic signal propagates
through a system. The propaga-
tion delay from low to high (tPLH)
is the amount of time required for
an input signal to propagate to
the output, causing the output to
change from low to high.
Similarly, the propagation delay
from high to low (tPHL) is the
amount of time required for the
input signal to propagate to the
output causing the output to
change from high to low (see
Figure 8).
Pulse-width distortion (PWD)
results when tPLH and tPHL differ in
value. PWD is defined as the
difference between tPLH and tPHL
and often determines the
maximum data rate capability of a
transmission system. PWD can be
expressed in percent by dividing
the PWD (in ns) by the minimum
pulse width (in ns) being
transmitted. Typically, PWD on
the order of 20-30% of the
minimum pulse width is tolerable;
the exact figure depends on the
particular application (RS232,
RS422, T-l, etc.).
Propagation delay skew, tPSK, is
an important parameter to
consider in parallel data applica-
tions where synchronization of
signals on parallel data lines is a
concern. If the parallel data is
being sent through a group of
optocouplers, differences in
propagation delays will cause the
data to arrive at the outputs of the
optocouplers at different times. If
this difference in propagation
delays is large enough, it will
determine the maximum rate at
which parallel data can be sent
through the optocouplers.
Propagation delay skew is defined
as the difference between the
minimum and maximum
propagation delays, either tPLH or
tPHL, for any given group of
optocouplers which are operating
under the same conditions (i.e.,
the same drive current, supply
voltage, output load, and
operating temperature). As
illustrated in Figure 19, if the
inputs of a group of optocouplers
are switched either ON or OFF at
the same time, tPSK is the
difference between the shortest
propagation delay, either tPLH or
tPHL, and the longest propagation
delay, either tPLH or tPHL.
As mentioned earlier, tPSK can
determine the maximum parallel
data transmission rate. Figure 20
is the timing diagram of a typical
parallel data application with both
the clock and the data lines being
sent through optocouplers. The
figure shows data and clock
signals at the inputs and outputs
of the optocouplers. To obtain the
maximum data transmission rate,
both edges of the clock signal are
being used to clock the data; if
only one edge were used, the
clock signal would need to be
twice as fast.
Propagation delay skew repre-
sents the uncertainty of where an
edge might be after being sent
through an optocoupler. Figure
20 shows that there will be
uncertainty in both the data and
the clock lines. It is important
that these two areas of uncertainty
not overlap, otherwise the clock
signal might arrive before all of
the data outputs have settled, or
some of the data outputs may
start to change before the clock
signal has arrived. From these
considerations, the absolute
minimum pulse width that can be
sent through optocouplers in a
parallel application is twice tPSK. A
cautious design should use a
slightly longer pulse width to
ensure that any additional
uncertainty in the rest of the
circuit does not cause a problem.
The tPSK specified optocouplers
offer the advantages of
guaranteed specifications for
propagation delays, pulsewidth
distortion and propagation delay
skew over the recommended
temperature, input current, and
power supply ranges.
