The ACSL-6xx0 series optocouplers feature the GaAsP
LEDs with proprietary back emission design. They offer
the designer a broad range of input drive current, from
7 mA to 15 mA, thus providing greater flexibility in
designing the drive circuit.
The output detector integrated circuit (IC) in the opto-
coupler consists of a photodiode at the input of a two-
stage amplifier that provides both high gain and high
bandwidth. The secondary amplifier stage of the detector
IC feeds into an open collector Schottky-clamped transis-
tor.
The entire output circuit is electrically shielded so that any
common-mode transient capacitively coupled from the LED
side of the optocoupler is diverted from the photodiode
to ground. With this electric shield, the optocoupler can
withstand transients that slopes up to 10,000V/μs, and am-
plitudes up to 1,000V.

Electrostatic Discharge Sensitivity
This product has been tested for electrostatic sensitivity
to the limits stated in the specifications. However, Avago
recommends that all integrated circuits be handled with
appropriate care to avoid damage. Damage caused by
inappropriate handling or storage could range from per-
formance degradation to complete failure.
Notes:
9. VISO is a dielectric voltage rating that should not be interpreted as an input-output continuous voltage rating. For continuous voltage rating,
refer to the IEC/EN/DIN EN 60747-5-2 Insulation Characteristics Table (if applicable), the equipment level safety specification or Avago Applica-
tion Note 1074 entitled “Optocoupler Input-Output Endurance Voltage.”
10. Measured between each input pair shorted together and all output connections for that channel shorted together.
11. In accordance to UL1577, each optocoupler is proof tested by applying an insulation test voltage ≥ 3000 Vrms for 1 sec (leakage detection
current limit, II-O ≤ 5 μA). This test is performed before the 100% production test for partial discharge (Method b) shown in the IEC/EN/DIN EN
60747-5-2 Insulation Characteristics Table, if applicable.
12. Measured between inputs with the LED anode and cathode shorted together.

Application Information
ON and OFF Conditions
The ACSL-6xx0 series has the ON condition defined by
current, and the OFF condition defined by voltage. In order
to guarantee that the optocoupler is OFF, the forward
voltage across the LED must be less than or equal to
0.8 volt for the entire operating temperature range. This
has direct implications for the input drive circuit. If the
design uses a TTL gate to drive the input LED, then one has
to ensure that the gate output voltage is sufficient to cause
the forward voltage to be less than 0.8 volt. The typical
threshold current for the ACSL-6xx0 series optocouplers is
2.7 mA; however, this threshold could increase over time
due to the aging effects of the LED. Drive circuit arrange-
ments must provide for the ON state LED forward current
of at least 7 mA, or more if faster operation is desired.
Maximum Input Current and Reverse Voltage
The average forward input current should not exceed
the 15 mA Absolute Maximum Rating as stated; however,
peaking circuits with transient input currents up to 50 mA
are allowed provided the average current does not exceed
15 mA. If the input current maximum rating is exceeded,
the local temperature of the LED can rise, which in turn may
affect the long-term reliability of the device. When designing
the input circuit, one must also ensure that the input reverse
voltage does not exceed 5V. If the optocoupler is subjected
to reverse voltage transients or accidental situations that
may cause a reverse voltage to be applied, thus an anti-
parallel diode across the LED is recommended.
Suggested Input Circuits for
Driving the LED
Figures 18, 19, and 20 show some of the several techniques
for driving the ACSL-6xx0 LED. Figure 18 shows the rec-
ommended circuit when using any type of TTL gate. The
buffer PNP transistor allows the circuit to be used with
TTL or CMOS gates that have low sinking current capabil-
ity. One advantage of this circuit is that there is very little
variation in power supply current due to the switching of
the optocoupler LED. This can be important in high-reso-
lution analog-to-digital (A/D) systems where ground loop
currents due to the switching of the LEDs can cause distor-
tion in the A/D output.
Figure 18. TTL interface circuit for the ACSL-6xx0.
17
With a CMOS gate to drive the optocoupler, the circuit
shown in Figure 19 can be used. The diode in parallel to
the current limiting resistor speeds the turn-off of the
optocoupler LED. Any HC or HCT series CMOS gate can
be used in this circuit.
For high common-mode rejection applications, the drive
circuit shown in Figure 20 is recommended. In this circuit,
only an open-collector TTL, or an open drain CMOS gate
can be used. This circuit drives the optocoupler LED with
a 220 ohm current-limiting resistor to ensure that an IF
of 7 mA is applied under worst case conditions and thus
guarantee the 10,000 V/μs optocoupler common mode
rejection rating. The designer can obtain even higher
common-mode rejection performance than 10,000 V/μs
by driving the LED harder than 7 mA.
Phase Relationship to Input
The output of the optocoupler is inverted when
compared to the input. The input is defined to be logic
HIGH when the LED is ON. If there is a design that requires
the optocoupler to behave as a non-inverting gate, then
Figure 20. High CMR drive circuit for the ACSL-6xx0.
Figure 21. High voltage switching with ACSL-6xx0.
Figure 22. High voltage and high current switching
with ACSL-6xx0.
Figure 19. CMOS drive circuit for the ACSL-6xx0.
the series input drive circuit shown in Figure 19 can be
used. This input drive circuit has an inverting function,
and since the optocoupler also behaves as an inverter,
the total circuit is non-inverting. The shunt drive circuits
shown in Figures 18 and 20 will cause the optocoupler to
function as an inverter.
Current and Voltage Limitations
The absolute maximum voltage allowable at the output
supply voltage pin and the output voltage pin of the opt-
ocoupler is 7 volts. However, the recommended maximum
voltage at these two pins is 5.5 volts. The output sinking
current should not exceed 13 mA in order to make the
Low Level Output Voltage be less than 0.6 volt. If the
output voltage is not a consideration, then the absolute
maximum current allowed through the ACSL-6xx0 is 50
mA. If the output requires switching either higher currents
or voltages, output buffer stages as shown in Figures 21
and 22 are suggested.

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 16).
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 synchro-
nization of signals on parallel data lines is a concern. If
the parallel data is being sent through a group of op-
tocouplers, 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 optocou-
plers.
Propagation delay skew is defined as the difference
between the minimum and maximum propagation
delays,either tPLH or tPHL, for any given group of optocou-
plers which are operating under the same conditions (i.e.,
the same drive current, supply voltage, output load, and
operating temperature). As illustrated in Figure 23, 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 24 is the timing
diagram of a typical parallel data application with both
the clock and the data lines being sent through opto-
couplers. 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 op-
tocoupler. Figure 24 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, pulse-
width distortion and propagation delay skew over the
recommended temperature, input current, and power
supply ranges.
