Fairchild Semiconductor has developed the FOD8012, full duplex, bi-directional, logic gate optocoupler with high noise immunity as well as reliable optical isolation for industrial fieldbus communications, programmable logic control, and servo control, as well as inverter, factory automation, process control and test and measurement applications.
The FOD8012 supports isolated communications of digital signals between systems without conducting ground loops or hazardous voltages. It features a 0.4mm (minimum) optical isolation gap, as well as a fast switching speed, up to 15Mbit/s. In addition, it employs Fairchild's proprietary Optoplanar packaging technology and optimized IC design to achieve high common mode rejection (CMR) of 20kV/µs minimum.
