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.

FODM8071 — 3.3V/5V Logic Gate Output Optocoupler with High Noise Immunity
December 2014
FODM8071
3.3V/5V Logic Gate Output Optocoupler with
High Noise Immunity
Features
■
High-noise Immunity Characterized by Common
Description
The FODM8071 is a 3.3V/5V high-speed logic gate
output optocoupler, which supports isolated communica-
tions allowing digital signals to communicate between
systems without conducting ground loops or hazardous
voltages. It utilizes Fairchild’s patented coplanar packag-
ing technology, Optoplanar
®
, and optimized IC design to
achieve high-immunity, characterized by high common
mode rejection specifications.
This high-speed logic gate output optocoupler, housed in
a compact 5-pin Mini-Flat package, consists of a high-
speed AlGaAs LED at the input coupled to a CMOS
detector IC at the output. The detector IC comprises an
integrated photodiode, a high-speed transimpedance
amplifier and a voltage comparator with an output driver.
The CMOS technology coupled with a high-efficiency
LED achieves low power consumption as well as very
high speed (55 ns propagation delay, 20 ns pulse width
