Features
Description
• 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°Cto70°C
• LSTTL compatible
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 ) permits lower output saturation voltage and higher
CC
• High output current – 60mA
• Safety approval:
speed operation than possible with conventional photo-
darlington type optocouplers. In addition, VCC may be as
low as 1.6V without adversely affecting the parametric
performance.
UL recognized – 3750 V rms for 1 minute and
5000Vrms* for 1 minute
CSA approved
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.
• 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
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
