Logic Gate Optocouplers offer high noise immunity.

Press Release Summary:

Combining noise immunity of 20 kV/µs with speeds of 25 Mbps, FOD07xx Series isolates logic control circuitry from transceiver at bus interface level, minimizing chance of transmission errors or system failures. Optoplanar® co-planar packaging reduces package capacitance, optimizing Common Mode Noise Rejection rating. Qualified according to UL1577 standard, FOD07xx Series is suited for industrial communication standards such as Profibus, DeviceNet, CAN, and RS485.

Original Press Release:

Fairchild Semiconductor's High Speed Logic Gate Optocouplers Offer Industry's Highest Noise Immunity (20kV/µs)

The FOD07xx Series Provides High Bandwidth (25Mbps) for the Isolation of Industrial Communication Applications

SAN JOSE, Calif. - July 8, 2008 - Fairchild Semiconductor (NYSE: FCS) brings designers an optocoupler solution that delivers a fast and robust isolation interface to ensure low transmission error rates and proven reliability for noisy industrial environments. The FOD0721, FOD0720 and FOD0710 are logic gate optocouplers that isolate the logic control circuitry from the transceiver at the bus interface level. Since industrial systems are susceptible to noise transients, FOD07xx's high noise immunity coupled with its high speed (25Mbps) minimizes the chance of transmission errors or system failures. These products meet high reliability requirements and are qualified according to the UL1577 standard. The FOD07xx series is ideal for industrial communication standards such as Profibus, DeviceNet, CAN and RS485.

The FOD07xx series are packaged in Fairchild's patented Optoplanar® packaging. This co-planar packaging reduces package capacitance by more than 30 percent compared to competitive solutions. This low capacitance package leads to a guaranteed 20kV/µs minimum Common Mode Noise Rejection rating that is double that of alternative solutions, allowing the FOD07xx series to operate in noisy industrial environments.

The FOD07xx series is part of Fairchild's comprehensive optoelectronic portfolio that includes high-speed optocouplers, gate drive optocouplers, snubberless triac driver, photo transistors, and infrared components. Fairchild offers a broad range of package platforms, input/output configurations and safety regulatory standards to meet the needs of many designs.

The FOD0721, FOD0720 and FOD0710 utilize lead-free (Pb-free) terminals and have been characterized for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/JEDEC standard J-STD-020. All of Fairchild's products are designed to meet the requirements of the European Union's Directive on the restriction of the use of certain substances (RoHS).
