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 cir-

cuitry which meets FCC 68.302 and other regulatory

voltage surge requirements when overvoltage protec-

tion is provided.
