Industrial communication design engineers need to send high-speed data through the communication field bus while avoiding damage to sensitive controllers, analog-to-digital converters or sensors. Existing solutions use two single-channel optocouplers or other technologies such as magnetic and capacitive coupling, but these methods cannot achieve the required level of reliable isolation and electromagnetic interference resistance.

To help designers meet these challenges, Fairchild Semiconductor has developed the industry’s first full-duplex, bidirectional logic gate optocoupler, the FOD8012, which features high noise immunity and proven reliable optical isolation for applications such as industrial fieldbus communications, programmable logic control, servo control, as well as inverters, factory automation, process control, and test and measurement.

The FOD8012 supports isolated communication of digital signals between systems without conducting ground loops or hazardous voltages. Unlike similar devices that offer optical isolation gaps less than 0.1mm, the FOD8012 has an optical isolation gap of 0.4mm (minimum) for proven reliable optical isolation. The device also features a conversion speed of up to 15Mbit/s and uses Fairchild Semiconductor's proprietary Optoplanar packaging technology and optimized integrated circuit design to achieve a high common mode rejection ratio (CMR) of 20kV/µs minimum, enabling the device to be used in noisy industrial environments.

The FOD8012 high-speed logic gate optocoupler is highly integrated, integrating two optical coupling channels in a bidirectional configuration in a compact 8-pin small package. Each optocoupler channel consists of a high-speed AIGaAs LED driven by a CMOS buffer IC coupled to a CMOS detector IC.

In addition, FOD8012 has a wide industrial temperature range of -40 to +110ºC and uses a 3.3V or 5V supply voltage to achieve logic level conversion. The high isolation voltage performance of the device is certified by UL1577 and IEC60747-5-2 for higher reliability.

FOD8012 is a member of Fairchild Semiconductor's extensive high-performance optocoupler product line, helping customers achieve design innovation. FOD8012 uses proprietary Optoplanar coplanar packaging technology to achieve the best noise immunity in its class. Optoplanar technology ensures a safe isolation thickness of more than 0.4mm, achieving reliable high-voltage isolation that meets UL1577 and IEC60747-5-2 certification standards.
