LAA110L
Dual Pole OptoMOS®Relays
LAA110L is a Dual 1 Form-A solid state relay that has
two independently controlled optically coupled
MOSFETs with an additional current limiting circuit.
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 opera-
tional 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.
