3.3V/5V, High-Speed Logic Gate Optocoupler with
Excellent Noise Immunity
Customer Presentation
December 2009

Optoplanar® Technology
The High Speed Optocoupler family utilizes Fairchild’s patented coplanar
packaging technology, Optoplanar®, and optimized IC design to guarantee
minimum 20kV/μs Common Mode Transient Immunity (CMTI).
Competitive Advantages
 High CMTI. This construction eliminates the capacitive charge buildup
that occurs in the over-under construction.
Fixed isolation gap (thickness through insulation). So a consistent high
input to output isolation voltage

High Noise Immunity, Logic Gate
Optocoupler in MFP 5-Pin
 By combining the reliable isolation,
excellent noise immunity
characteristics, small footprint of an
optocoupler with the high data rate
capability, the FODM8071,
FODM8061 and FODM611 allow
system engineers to design a
robust system, with low
transmission error rate, low system
failure rate, a proven reliability over
extended periods of time required
for Industrial systems, at a low cost
of design and component.

Value Propositions
 FOD8001 and FOD07xx Series are positioned as improved replacement to
Avago’s ACPL-072L, HCPL-07xx; electrical and pin-out compatible as drop-in
replacement, eg. FOD0721 vs HCPL-0721.
 Value proposition includes higher CMTI, wide temperature range and lower
power consumption.

Applications - Optically Isolating
High Speed Interface (1)
Fairchild’s high performance optocouplers have a superior common mode transient immunity advantage (>30%
over competition). With their high speed data rates, these optocouplers are ideal for high speed data
communications. Portable and compact electronic devices require optocouplers that reduce power consumption
and save space. The 3.3V supply voltage specification reduces power consumption by 33%, while 5-pin MFP and
dual channel 8-pin SOP packaging optimize mounting density.
