No. 7980 FIMKO Approval CSA – Certification 093751 APPLICATIONS General Telecom Switching – On/off Hook Control – Ring Delay – Dial Pulse – Ground Start – Ground Fault Protection Instrumentation Industrial Controls See Application Note 56 DESCRIPTION The LH1540 is robust, ideal for telecom and ground fault applications. It is a SPST normally open switch (1 Form A) that replaces electromechanical relays in many applications. 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 FCC 68.302 and other regulatory voltage surge requirements when overvoltage protection is provided.
