onsemi | FOD8001

The FOD8001 is a 3.3 V/5 V high-speed logic gate Optocoupler, which supports isolated communications allowing digital signals to communicate between systems without conducting ground loops or hazardous voltages. It utilizes Fairchild’s proprietary coplanar packaging technology, Optoplanar®, and optimized IC design to 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 highspeed 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.
