Description
LAA110 is a Dual 1 Form-A solid state relay that has two
independently controlled optically coupled MOSFETs. The
efficient MOSFET switches and photovoltaic die use
Clare’s patented OptoMOS® architecture to provide 3750
VRMS of input to output isolation. The optically coupled
inputs are controlled by highly efficient GaAIAs infrared
LEDs. Dual pole OptoMOS relays provide a more compact
design solution than discrete single pole relays in a variety
of applications. The dual pole relays save board space by
incorporating both relays in a single 8-pin 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 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.
