Description
The LH1540 is robust, ideal for telecom and ground
fault applications. It is a SPST normally open switch
(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 com-
prised of a photodiode array, switch control circuitry
and MOSFET switches. In addition, it employs cur-
rent-limiting circuitry which meets FCC 68.302 and
other regulatory voltage surge requirements when
overvoltage protection is provided.
