Description
The FOD8001 is a 3.3V/5V high-speed logic gate
Optocoupler, which supports isolated communications
allowing digital signals to communicate between sys-
tems without conducting ground loops or hazardous
voltages. It utilizes Fairchild’s patented coplanar packag-
ing technology, Optoplanar
achieve high noise immunity, characterized by high
common mode rejection and power supply rejection
specifications.
This high-speed logic gate optocoupler, packaged in a
compact 8-pin small outline package, consists of a high-
speed AlGaAs LED driven by a CMOS buffer IC coupled
to a CMOS detector IC. The detector IC comprises an
integrated photodiode, 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).
