High Noise Immunity, 3.3 V / 5 V Logic Gate Optocoupler FOD8001 Description www.onsemi.com The FOD8001 is a 3.3 V / 5 V highspeed logic gate optocoupler, which supports isolated communications allowing digital signals to communicate between systems without conducting ground loops or hazardous voltages. It utilizes ON Semiconductor patented 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 highspeed logic gate optocoupler, packaged in a compact 8pin small outline package, consists of a highspeed AlGaAs LED SOIC8 driven by a CMOS buffer IC coupled to a CMOS detector IC. The CASE 751DZ detector IC comprises an integrated photodiode, a highspeed transimpedance amplifier and a voltage comparator with an output driver. The CMOS technology coupled to the high efficiency of the MARKING DIAGRAM LED achieves low power consumption as well as very high speed 1 (40ns propagation delay, 6ns pulse width distortion).
