Description
The FODM8071 is a 3.3V/5V high-speed logic gate
output Optocoupler, which supports isolated communi-
cations allowing digital signals to communicate between
systems without conducting ground loops or hazardous
voltages. It utilizes Fairchild’s patented coplanar packag-
ing technology, Optoplanar
achieve high noise immunity, characterized by high com-
mon 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 (55ns propagation delay, 20ns pulse width
distortion).
