Overview
The FODM8061R2 is a 3.3V/5V high-speed logic gate output (open collector) optocoupler produced by onsemi. This component supports isolated communications, allowing digital signals to communicate between systems without conducting ground loops or hazardous voltages. It utilizes onsemi’s proprietary coplanar packaging technology, Optoplanar®, and optimized IC design to achieve high noise immunity. The optocoupler consists of an AlGaAS LED at the input, optically coupled to a high-speed integrated photodetector logic gate. The output of the detector IC is an open collector Schottky-clamped transistor, ensuring reliable and high-speed signal transmission over a wide temperature range of -40°C to +110°C.
