N Multifunction Telecom Switch N Units Load Voltage 3 V Load Current ma Max R ON Ω Features Small 8 Pin SOIC Narrow Package Low Drive Power Requirements (TTL/CMOS Compatible) No Moving Parts High Reliability Arc-Free With No Snubbing Circuits V RMS Input/Output Isolation FCC Compatible VDE Compatible No EMI/RFI Generation Machine Insertable, Wave Solderable Tape & Reel Version Available Description The Multifunction Telecom switch combines a 3V Form A relay and an optocoupler in a single package. The relay uses optically coupled MOSFET technology to provide V 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. N allows telecom circuit designers to combine two discrete functions, such as hook switch and ring detect, in a single component. The s small package uses less space than traditional discrete component solutions.
