HCPL-2730/0730/2731/0731
Dual Channel Low Input Current, High Gain Optocouplers
Data Sheet
Lead (Pb) Free
RoHS 6 fully
compliant
RoHS 6 fully compliant options available;
-xxxE denotes a lead-free product
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 first gain stages
(V
CC
) permits lower output saturation voltage and higher
speed operation than possible with conventional photo-
darlington type optocouplers. In addition, V
CC
may be as
low as 1.6 V 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.

Features
• High current transfer ratio – 1800% typical
• Low input current requirements – 0.5 mA
• Low output saturation voltage – 0.1 V
• High density packaging
• Performance guaranteed over temperature 0°C to 70°C
• LSTTL compatible
• High output current – 60 mA
• Safety approval:
UL recognized – 3750 V rms for 1 minute and
5000 V rms* for 1 minute
CSA approved
• Available in 8 pin DIP and SO-8 footprint
• MIL-PRF-38534 hermetic version available
(HCPL-5730/5731)
• Surface mount gull wing option available for 8-pin DIP
(Option 300)
Applications
• Digital logic ground isolation
• Telephone ring detector
• Level shifting
• EIA RS-232C line receiver
• Polarity sensing
• Low input current line receiver – long line or party line
• Microprocessor bus isolation
• Current loop receiver
• Line voltage status indicator – low input power dissipa-
tion
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.

and/or degradation which may be induced by ESD.
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 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 V
CC
and V
O
specifica-
tions and by testing output high leakage (I
OH
) at 18 V.
The HCPL-2730/0730 are specified at an input current of 1.6
mA and have a 7 V V
CC
and V
O
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.
