TS112N

DS-TS112N-R2

The TS112 Multifunction Telecom switch combines a
350V Form A relay and an optocoupler in a single pack­age. The relay uses optically coupled MOSFET technolo­gy 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. TS112N
allows telecom circuit designers to combine two discrete
functions, such as hook switch and ring detect, in a single
component. The TS112’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.
