DESCRIPTION
The LH1521 dual 1 Form B relays are SPST normally
closed switches that can replace electromechanical
relays in many applications. They are constructed using
a GaAIAs LED for actuation control and an integrated
monolithic die for the switch output. The die, fabricated
in a high-voltage dielectrically isolated technology is
comprised of a photodiode array, switch control cir-
cuitry, and MOSFET switches.
