The LCA110L is a 1-Form-A solid state relay which
uses optically coupled MOSFET technology to pro-
vide 3750V of input to output isolation. The efficient
MOSFET switches and photovoltaic die use Clare's
patented OptoMOS architecture. The optically-cou-
pled input is controlled by a highly efficent GaAIAs
infrared LED. The LCA110L can be used to replace
mechanical relays and offers the superior reliability
associated with semiconductor devices. Because
they have no moving parts, they can offer faster,
bounce-free switching in a more compact surface
mount or through hole package.

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.
