Dissipation
These dual channel optocouplers
contain a separated pair of GaAsP
light emitting diodes optically
coupled to a pair of integrated
high gain photo detectors. They
provide extremely high current
transfer ratio and excellent inputoutput common mode transient
immunity. A separate pin for the
photodiodes and first gain stages
(VCC) permits lower output saturation voltage and higher speed
operation than possible with
conventional photodarlington
type optocouplers. In addition,
VCC may be as low as 1.6 V

*5000 V rms/1 minute withstand voltage rating is for Option 020 (HCPL-2730, HCLP-2731) products only.
A 0.1 µF bypass capacitor connected between pins 5 and 8 is recommended.
CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to
prevent damage and/or degradation which may be induced by ESD.

without adversely affecting the
parametric performance.
These dual channel optocouplers
are available in an 8-Pin DIP and
in an industry standard SO-8
package. The following is a cross
reference table listing the 8-Pin
DIP part number and the
electrically equivalent SOIC-8 part
number.

HCPL-2730 HCPL-0730
HCPL-2731 HCPL-0731
The SO-8 does not require
“through holes” in a PCB. This
package occupies approximately
one-third the footprint area of the
standard dual-in-line package.
The lead profile is designed to be
compatible with standard surface
mount processes.
Guaranteed operation at low input
currents and the high current
transfer ratio (CTR) reduce the
magnitude and effects of CTR
degradation.
The outstanding high temperature
performance of this split
Darlington type output amplifier
results from the inclusion of an
integrated emitter-base bypass
resistor which shunts photodiode
and first stage leakage currents to
ground.
The HCPL-2731/0731 have a
400% minimum CTR at an input
current of only 0.5 mA making it
ideal for use in low input current
applications such as MOS, CMOS,
and low power logic interfacing or
RS232C data transmission
systems. In addition, the high
CTR and high output current
capability make this device
extremely useful in applications
where a high fanout is required.
Compatibility with high voltage
CMOS logic systems is guaranteed
by the 18 V VCC and VO specifications and by testing output high
leakage (IOH) at 18 V.
The HCPL-2730/0730 are specified at an input current of 1.6 mA
and have a 7 V VCC and VO rating.
The 300% minimum CTR allows
TTL to TTL interfacing at this
input current.
Important specifications such as
CTR, leakage current, and output
saturation voltage are guaranteed
over the 0°C to 70°C temperature
range to allow trouble-free system
operation. Selection for lower
input currents down to 250 µA is
available upon request.

**The Input-Output Momentary Withstand Voltage is a dielectric voltage rating that should not be interpreted as an input-output
continuous voltage rating. For the continuous voltage rating refer to the VDE 0884 Insulation Characteristics Table (if applicable), your equipment level safety specification or HP Application Note 1074 entitled “Optocoupler Input-Output Endurance
Voltage.”
Notes:
1. Pin 5 should be the most negative
voltage at the detector side.
2. Each channel.
3. DC CURRENT TRANSFER RATIO
(CTR) is defined as the ratio of output
collector current, IO, to the forward
LED input current, IF, times 100%.
4. Device considered a two-terminal
device: pins 1, 2, 3, and 4 shorted
together, and pins 5, 6, 7, and 8
shorted together.
5. Measured between pins 1 and 2
shorted together, and pins 3 and 4
shorted together.
6. Common mode transient immunity in a
Logic High level is the maximum
tolerable (positive) dVCM /dt of the
common mode pulse, VCM, to assure
that the output will remain in a Logic
High state (i.e., VO > 2.0 V). Common
mode transient immunity in a Logic
Low level is the maximum tolerable
(negative) dVCM/dt of the common
mode pulse, VCM, to assure that the
output will remain in a Logic Low state
(i.e., VO < 0.8 V).
7. In applications where dV/dt may
exceed 50,000 V/µs (such as static
discharge) a series resistor, RCC,
should be included to protect the
detector IC from destructively high
surge currents. The recommended
value is RCC = 110 Ω.
8. Use of a 0.1 µF bypass capacitor
connected between pins 5 and 8
adjacent to the device is
recommended.
9. In accordance with UL 1577, each
optocoupler is proof tested by
applying an insulation test voltage
> 3000 V rms for 1 second (leakage
detection current limit, II-O < 5 µA).
10. In accordance with UL 1577, each
optocoupler is proof tested by
applying an insulation test voltage
> 6000 V rms for 1 second (leakage
detection current limit, II-O < 5 µA).
11. Measured between the LED anode and
cathode shorted together and pins 5
through 8 shorted together.
12. Derate linearly above 65°C free-air
temperature at a rate of 2.3 mW/°C for
the SO-8 package.
