The LCA210 is a common input 1-Form 2A solid state relay
which has two independent optically couple MOSFETS
controlled by a common input signal. The efficient MOS-
FET switches and photovoltaic die use Clare’s patented
OptoMOS
®
architecture to provide 3750 V
RMS
of input to
output isolation. The optically coupled input is controlled by
highly efficient GaAIAs infrared LEDs. Common input
OptoMOS relays can replace standard dual pole relays in
a variety of applications. The common input relay elimi-
nates the need to make an external circuit connection
when both poles are controlled by a common signal.

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
operational sections of this data sheet is not implied.
Exposure of the device to the absolute maximum ratings
for an extended period may degrade the device and effect
its reliability.
