It is an SPST normally open switch (1 form A) that replaces electromechanical relays in many applications. It is similar to the LH1540, but has a characteristically higher On resistance. It is 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 circuitry and MOSFET switches. In addition, it employs current-limiting circuitry which meets lightning surge testing as per ANSI/TIA-968-B and other regulatory voltage surge requirements when overvoltage protection is provided. • General telecom switching • Instrumentation • Industrial controls AGENCY APPROVALS UL1577: file no.
