Description
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 excel-
lent input-output common mode transient immunity. A
separate pin for the photodiodes and rst gain stages
(VCC) permits lower output saturation voltage and higher
speed operation than possible with conventional photo-
darlington type optocouplers. In addition, VCC may be as
low as 1.6 V without adversely aecting 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.
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 prole
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 amplier results from the inclusion
of an integrated emitter-base bypass resistor which shunts
photodiode and rst 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 cur-
rent applications such as MOS, CMOS, and low power logic
interfacing or RS232C data transmission systems. In addi-
tion, 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 specica-
tions and by testing output high leakage (IOH) at 18 V.
The HCPL-2730/0730 are specied 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 cur-
rent, and output saturation voltage are guaranteed
over the 0°C to 70°C temperature range to allow
trouble-free system operation. Selection for lower in-
put currents down to 250 µA is available upon request.

Notes:
1. Pin 5 should be the most negative voltage at the detector side.
2. Each channel.
3. DC CURRENT TRANSFER RATIO (CTR) is dened 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) dV
CM/dt of the common mode pulse, VCM, to as-
sure 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 detec-
tor 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 > 4500 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.

**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 IEC/EN/DIN EN 60747-5-2 Insulation Characteristics Table (if applicable), your equip-
ment level safety specication or Avago Application Note 1074 entitled “Optocoupler Input-Output Endurance Voltage.”
