The IAD112N Multifunction Telecom switch combines a
350V Form A relay and two optocouplers in a single pack-
age. The relay uses optically coupled MOSFET technolo-
gy to provide 1500V of input to output isolation. The
efficient MOSFET switch and photovoltaic die use Clare’s
patented OptoMOS architecture. The optically coupled
input uses highly efficient GaAIAs infrared LEDs.
IAD112N’s allow telecom circuit designers to combine
three discrete functions in a single component. The
IAD112N’s small package uses less space than tradition-
al 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.
