Optocoupler lessens transmission errors

Fairchild Semiconductor offers designers an optocoupler solution that the company claims delivers a fast and robust isolation interface to ensure low transmission error rates and reliability for noisy industrial setups. 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) minimises 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. According to Fairchild, 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 FOD0721, FOD0720 and FOD0710 utilise Pb-free terminals and have been characterised for moisture sensitivity. For 10,000 units, the FOD0721 sell for Rs.106.86 ($2.67) apiece, Rs.97.65 ($2.44) for the FOD0720 and 2.21 for the FOD0710. Sample units are available now.
