Logic Gate Optocouplers Offer 20kV/µs Noise Immunity

(Product News, 14 Jul 2008)

Fairchild Semiconductor's latest optocoupler solutions, the FOD0721, FOD0720 and FOD0710, deliver a fast and robust isolation interface to ensure low transmission error rates and proven reliability for noisy industrial environments. The latest logic gate optocouplers 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 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, which reduces package capacitance by more than 30 percent compared to competitive solutions. This low capacitance package leads to a guaranteed 20kV/µs Common Mode Noise Rejection rating that is double that of alternative solutions.

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).
