The IAD112N Multifunction Telecom switch combines a 350V Form A relay and two optocouplers in a single package. The relay uses optically coupled MOSFET technology to provide 1500V of input to output isolation. The efficient MOSFET switch and photovoltaic die use Clare's patented OptoMOS architecture. The optically coupled input uses highly efficient GaAIAs infrared LEDs. IAD112N's allow telecom circuit designers to combine three discrete functions in a single component. The IAD112N's small package uses less space than traditional discrete component solutions.
