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

FOD073L — LVTTL/LVCMOS Compatible Low Input Current High Gain Split Darlington Optocoupler
April 2009
FOD073L
LVTTL/LVCMOS Compatible Low Input Current
High Gain Split Darlington Optocoupler
Features
■
Low power consumption
■
Low input current: 0.5mA
■
Dual channel 8-pin SOIC package
■
High CTR: 400% minimum
■
High CMR: 10kV/µs
■
Guaranteed performance over temperature
Description
The FOD073L optocoupler consists of an AlGaAs LED
optically coupled to a high gain split darlington photo-
detector. This device is specified to operate at a 3.3V
supply voltage.
An integrated emitter – base resistor provides superior
stability over temperature.
The combination of a very low input current of 0.5mA
and a high current transfer ratio of 2000% (typical)
makes this device particularly useful for input interface to
MOS, CMOS, LSTTL and EIA RS232C, while output
compatibility is ensured to LVCMOS as well as high
fan-out LVTTL requirements.
An internal noise shield provides exceptional common
