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. Please
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

High CMR, 25Mbit/sec Logic Gate Optocoupler
Features
Description
■ 20kV/µs minimum CMR
The FOD0721/0720/0710 family utilizes Fairchild’s
proprietary coplanar packaging technology, Optoplanar®,
and optimized IC design to guarantee minimum 20kV/µs
Common Mode Noise Rejection (CMR) rating.
■ 40ns max. propagation delay
■ Data Rate, Non-Return Zero Coding
– 25Mbit/sec (FOD0721 and FOD0720)
– 12.5Mbit/sec (FOD0710)
These high-speed logic gate optocouplers consist of a
high-speed AlGaAs LED driven by a CMOS IC coupled
to a CMOS detector IC, comprising an integrated photo-
diode, a high-speed transimpedance amplifier and a
voltage comparator with an output driver. The CMOS
technology coupled to the high efficiency of the LED
achieves low power consumption as well as very high
speed (40ns propagation delay, 6ns pulse width
distortion).
■ Pulse Width Distortion
– 6ns (FOD0721)
– 8ns (FOD0720 and FOD0710)
■ +5V CMOS compatibility
■ Extended industrial temperate range
– -40 to 100°C temperature range
■ Safety and regulatory approvals
– UL1577, 3750 VACrms for 1 min. (File #E90700,
Volume 2)
These devices are available in a compact 8-pin small
outline package.
– IEC60747-5-2 pending approval
Applications
■ Industrial fieldbus communications
– Profibus, DeviceNet, CAN, RS485
■ Programmable logic control
■ Isolated data acquisition system

Absolute Maximum Ratings (T = 25°C unless otherwise specified.)
A
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
