FOD0721, FOD0720, FOD0710
High CMR, 25Mbit/sec Logic Gate Optocoupler
Features
Description
■ 20kV/µs minimum CMR
The FOD0721/0720/0710 family utilizes Fairchild’s
patented 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.

ANTI-COUNTERFEITING POLICY
Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website, www.fairchildsemi.com,
under Sales Support.
Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semiconductor products are experiencing counterfeiting of their parts.
Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed applications,
and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the proliferation of
counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild Distributors who are
listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors are genuine parts, have
full traceability, meet Fairchild's quality standards for handling and storage and provide access to Fairchild's full range of up-to-date technical and product information.
Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address any warranty issues that may arise. Fairchild will not provide
any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global problem and encourage our
customers to do their part in stopping this practice by buying direct or from authorized distributors.
