IAB110P
DS-IAB110P-R2
The IAB110P Multifunction Telecom switch combines a
350V Form A relay, 350V Form B relay and one optocou-
pler in a single package. The relay uses optically coupled
MOSFET technology to provide 1500V of input to output
isolation. The efficient MOSFET switches and photovolta-
ic die use Clare's patented OptoMOS architecture. The
optically coupled input uses highly efficient GaAIAs
infrared LEDs. IAB110P's allow telecom circuit designers
to combine three discrete functions in a single compo-
nent. The IAB110P's small package uses less space than
traditional discrete component solutions.

Absolute Maximum Ratings are stress ratings. Stresses
in excess of these ratings can cause permanent damage
to the device. Functional operation of the device at these
or any other conditions beyond those indicated in the
operational sections of this data sheet is not implied.
Exposure of the device to the absolute maximum ratings
for an extended period may degrade the device and effect
its reliability.
