XAA170 is a dual normally open (1-Form-A) solid
state relay with two independent, optically coupled
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.
