Description

The FOD8012 is a full duplex, bi-directional, 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 co-planar packaging technology, Optoplanar, and opti-IC design to achieve minimum 20kV/µs Common Mode Noise Rejection (CMR) rating.
