Introduction

LBB110 is a dual normally closed (1-Form-B) solid state relay that has two independently controlled, optically coupled MOSFET switches in an 8-pin SOIC package that employs optically coupled MOSFET technology to provide 3750Vrms of input to output isolation. Its optically coupled outputs, which use patented OptoMOS architecture, are controlled by a highly efficient infrared LED. Dual single-pole OptoMOS relays provide a more compact design solution than discrete single-pole relays in a variety of applications by incorporating both relays in a single 8-pin package.
