The dual 1-Form-A XAA170 solid state relay has
two independent, optically coupled, normally open
single-pole relays in a single 8-pin package. Clare's
patented OptoMOS architecture makes available the
optically coupled technology necessary to activate the
output's efficient MOSFET switches while providing
a 3750Vrms input-to-output isolation barrier. Control
of the isolated output is accomplished by means of a
highly effective GaAlAs infrared LED at the input.

By incorporating two independent single-pole relays
into a single 8-pin package, the XAA170 saves board
space by providing a more compact design solution
than two discrete single-pole relays in a variety of
applications.
