FOD8012 is a full duplex, bi-directional, high-speed logic gate optocoupler that supports isolated communication, allowing digital signals to be transmitted between systems without conducting ground loops. It features high common mode rejection (20kV/µs), high speed performance, 3.3V and 5V CMOS compatibility, extended industrial temperature range, etc.
The FOD8012 is a full duplex, bi-directional, high-speed logic gate optocoupler designed to support isolated communications between systems. It utilizes Fairchild's proprietary Optoplanar packaging technology and opti-IC design to achieve a minimum 20kV/us Common Mode Noise Rejection (CMR) rating. The device is housed in a compact 8-pin small outline package and features two optically coupled channels arranged in a bi-directional configuration.
