The KAQW214 series contains two normally open
switches that can be used as two independent SPST
relays or as one DPST relay. The relays is constructed
using a GaAlAs LED for actuation control and an
integrated monolithic dies for the switch output. The die,
fabricated in a high-voltage dielectrically isolated
technology, is comprised of a photodiode array, switch
control circuitry and MOSFET switches.
