The LCB110 is a 1-Form-B relay which uses optically
coupled MOSFET technology to provide 3750V of input
to output isolation. The efficient MOSFET switches and
photovoltaic die use Clare’s patented OptoMOS
®
archi-
tecture. A highly efficient GaAIAs infrared LED controls
the optically coupled input. The LCB110 has low on
resistance and is well suited for most applications
requiring a normally closed relay. The device is avail-
able in small 6-pin dual in line package in standard
though hole and surface mount lead bend.

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 opera-
tional sections of this data sheet is not implied. Exposure of
the device to the absolute maximum ratings for an extend-
ed period may degrade the device and effect its reliability.
