two independent, optically coupled MOSFET switches
On-Resistance (max) 20
controlled by a common input signal. It is provided
in an 8-pin package, and employs optically coupled
MOSFET technology to provide 3750V of input to

efficient GaAIAs infrared LED.
High Reliability
Arc-Free With No Snubbing Circuits
Common input OptoMOS relays can replace standard
FCC Compatible
dual-pole relays in a variety of applications. The
VDE Compatible
common input relay eliminates the need to make
