Since industrial systems are susceptible to noise transients, FOD07xx's high noise immunity coupled with its high speed (25-Mbit/s) 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 intended 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 products, 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 company added.
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.
Pricing: In 1,000-unit quantities is $2.67 for the FOD0721; $2.44 for the FOD0720; and $2.21 for the FOD0710.
Availability: Samples are available now; delivery is six weeks ARO.
Datasheets: FOD0721, FOD0720 and FOD0710.
