The IAA110P Multifunction Telecom switch combines
two 350V Form A relays and one optocoupler in a
single package. The relay uses optically coupled
MOSFET technology to provide 3750Vrms of input
to output isolation. The efficient MOSFET switches
and photovoltaic die use Clare’s patented OptoMOS
architecture. The optically coupled input uses highly
efficient GaAIAs infrared LEDs. The IAA110P allows
telecom circuit designers to combine three discrete
functions in a single component. The IAA110P’s
small package uses less space than traditional
discrete component solutions.
