The IAB110P Multifunction Telecom switch combines
one 350V single-pole, normally open (1-Form-A)
relay; one 350V single-pole, normally closed
(1-Form-B) relay; and one bidirectional optocoupler in
a single package. Optically coupled relay outputs that
use the patented OptoMOS architecture are

Features
controlled by a highly efficient infrared LED.
• 3750Vrms Input/Output Isolation
• Three Functions in One Package
• Bidirectional Current Sensing
• Bidirectional Current Switching
• FCC Compatible
The IAB110P allows telecom circuit designers to
combine three discrete functions in a single
component, whose small package uses less space
than traditional discrete component solutions.
• No EMI/RFI Generation
• Small 16-Pin SOIC Package
• Tape & Reel Versions Available
Approvals
