Fairchild Semiconductor FOD07xx Series high speed logic gate Optocoupler

Fairchild Semiconductor brings designers optocoupler devices that deliver 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) 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 co-planar packaging, which claims to reduce package capacitance by more than 30 per cent compared to other products. This low capacitance package leads to a guaranteed 20kV/µs minimum Common Mode Noise Rejection rating that is double that of alternative products, allowing the FOD07xx series to operate in noisy industrial environments. 

The FOD07xx series is part of Fairchild's optoelectronic portfolio that includes high-speed optocouplers, gate drive optocouplers, snubberless triac driver, photo transistors, and infrared components. The FOD0721, FOD0720 and FOD0710 use lead-free (Pb-free) terminals and have been characterised for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/JEDEC standard J-STD-020.

All Fairchild's products are designed to meet the requirements of the EU's directive on the restriction of the use of certain substances (RoHS).
