ACSL-6xx0 Data Sheet Multi-Channel and Bi-Directional, 15 MBd Digital Logic Gate Optocoupler
Schematic Diagrams
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 optocoupler
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 transistor.
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
amplitudes up to 1000V.

Application Information
ON and OFF Conditions
The ACSL-6xx0 series has the ON condition defined by
current, and the OFF condition defined by voltage. To
guarantee that the optocoupler is OFF, the forward voltage
across the LED must be less than or equal to 0.8V 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 0.8V. The typical threshold current
for the ACSL6xx0 series optocouplers is 2.7 mA; however,
this threshold could increase over time due to the aging
effects of the LED. Drive circuit arrangements 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
Figure 34, Figure 35, and Figure 36 show some of the
several techniques for driving the ACSL-6xx0 LED.
Figure 34 shows the recommended 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 capability. 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-resolution analog-to-digital (A/D) systems where
ground loop currents due to the switching of the LEDs can
cause distortion in the A/D output.

With a CMOS gate to drive the optocoupler, the circuit
shown in Figure 35 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 36 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
220Ω 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 7mA.
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 the series input
Figure 35: CMOS Drive Circuit for the ACSL-6xx0
Figure 36: High CMR Drive Circuit for the ACSL-6xx0
drive circuit shown in Figure 35 can be used. This input
drive circuit has an inverting function, and because the
optocoupler also behaves as an inverter, the total circuit is
non-inverting. The shunt drive circuits shown in Figure 34
and Figure 36 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
optocoupler is 7V. However, the recommended maximum
voltage at these two pins is 5.5V. The output sinking current
should not exceed 13 mA to make the Low Level Output
Voltage be less than 0.6V. If the output voltage is not a
consideration, 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 Figure 37 and Figure 38 are suggested.
