Overview
The FOD8012AR2 is a high-speed, bi-directional logic gate optocoupler produced by onsemi. This component is designed to support isolated communications between systems, preventing ground loops and hazardous voltages. It utilizes onsemi’s patented OPTOPLANAR® coplanar packaging technology and optimized IC design to achieve a minimum 20 kV/μs Common Mode Noise Rejection (CMR) rating. The FOD8012AR2 is highly integrated with two optically coupled channels arranged in a bi-directional configuration, housed in a compact 8-pin small outline package (SOIC8).
