Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at
www.onsemi.com.

Description
The HCPL0700, HCPL0701, HCPL0730 and HCPL0731
optocouplers consist of an AlGaAs LED optically coupled
to a high gain split darlington photodetector housed in a
compact 8-pin small outline package. The HCPL0730
and HCPL0731 devices have two channels per package
for optimum mounting density.
The split darlington configuration separating the input
photodiode and the first stage gain from the output tran-
sistor permits lower output saturation voltage and higher
speed operation than possible with conventional darling-
ton phototransistor optocoupler.
The combination of a very low input current of 0.5mA
and a high current transfer ratio of 2000% makes this
family particularly useful for input interface to MOS,
CMOS, LSTTL and EIA RS232C, while output compati-
bility is ensured to CMOS as well as high fan-out TTL
