Industry-first bi-directional logic gate optocoupler provides reliable optical isolation
January 17, 2011 // Paul Buckley
Fairchild Semiconductor is claiming an industry-first with a full duplex, bi-directional, logic gate optocoupler with high noise immunity as well as proven, reliable optical isolation.
The bi-directional optocoupler is ideal 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. Unlike competitive devices which provide less than 0.1mm optical isolation gap, the FOD8012 features a 0.4 mm (minimum) optical isolation gap for proven, reliable isolation. The device also features a fast switching speed, up to 15 Mbit/sec, and uses Fairchild’s proprietary Optoplanar - packaging technology and optimized IC design to achieve high common mode rejection (CMR) of 20 kV/us minimum, allowing the device to operate in noisy industrial environments.
The high-speed logic gate optocoupler is highly integrated with two optically coupled channels arranged in a bi-directional configuration, and housed in a compact 8-pin small outline package. Each optocoupler channel consists of a high-speed AIGaAs LED, driven by a CMOS buffer IC coupled to a CMOS detector IC.
Additionally, the FOD8012 offers an extended industrial temperature range of -40 to +110 degrees C and a 3.3 V or 5 V supply voltage to facilitate logic level translation. The device’s high isolation voltage is certified by UL1577 and IEC60747-5-2 for increased reliability.
Fairchild enables customers to drive innovation in their designs by developing solutions like the FOD8012 – which is part of Fairchild’s comprehensive portfolio of high performance optocouplers. The FOD8012 offer best-in-class noise immunity resulting from its proprietary Optoplanar coplanar packaging technology. The Optoplanar technology ensures safe insulation thickness of more than 0.4 mm in attaining reliable high voltage isolation, certified by UL1577 and IEC60747-5-2 standards.
Availability and Pricing
Samples of the FOD8012 are available now, priced at $3.08 (each, 1k pieces)
