The IAA110P Multifunction Telecom switch combines
two 350V normally open (1-Form-A) relays and one
optocoupler in a single package. The relays use
optically coupled MOSFET technology to provide
3750Vrms of input to output isolation. The efficient
MOSFET switches and photovoltaic die use IXYS
Integrated Circuits Division’s patented OptoMOS
architecture while the inputs' highly efficient GaAIAs
infrared LEDs control the outputs. The IAA110P
allows telecom circuit designers to combine
three discrete functions in a single component
that occupies less space than traditional discrete
component solutions.
