Units

The IAA110P Multifunction Telecom switch combines two
350V Form A relays and one optocoupler in a single pack-
age. The relay uses optically coupled MOSFET technolo-
gy to provide 1500V 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.
IAA110P allows telecom circuit designers to combine
three discrete functions in a single component. The
IAA110P’s small package uses less space than tradition-
al discrete component solutions.
