Fairchild Semiconductor’s Optocoupler Offers Excellent Isolation for Industrial Fieldbus Communications

SAN JOSE, Calif.—(BUSINESS WIRE)—March 2, 2009— Fairchild Semiconductor (NYSE: FCS) brings industrial system designers an optocoupler solution with excellent noise immunity. The FOD8001 answers the need for system engineers’ to design a robust industrial fieldbus network with low transmission error rates, low system failure rates and proven reliability over an extended period of time. Fairchild’s high performance optocouplers offer best-in-class noise immunity resulting from its proprietary coplanar packaging technology, Optoplanar ®. Its integrated circuits and light emitting diode (LED) are assembled on a coplanar process, rather than a face-to-face or over-under process, helping to reduce package capacitance between input and output and improving noise immunity. It features 25kV/µs@1,500Vcm dynamic Common Mode Transient Immunity (CMTI) rating under high-speed optocoupler switching and 40kV/µs@1,000Vcm static CMTI, making it more resilient to noise.

Its exceptionally high bandwidth (25Mbps) and tight pulse width distortion (6 nanoseconds) achieves the industry standard for field bus communications in automation technology such as Profibus, DeviceNet, CAN, Modbus, Interbus and many other standards. Its wide supply voltage range from 3V to 5.5V enables easy interfacing with low voltage devices, reducing overall system power. The FOD8001 also supports wide temperature range of -40ºC to +105ºC, which is important in industrial environments.
