Description
The TS117 integrated circuit device combines a 350V
normally open (1-Form-A) relay with an optocoupler
in a single package. The relay uses optically coupled
MOSFET technology to provide 3750Vrms of input to
output isolation.
Its optically coupled relay outputs, which use the
patented OptoMOS architecture, are controlled by a
highly efficient GaAIAs infrared LED.
The TS117 enables telecom circuit designers to
combine two discrete functions in a single component
that uses less space than traditional discrete
component solutions.
