DESCRIPTION
The LH1540 is robust, ideal for telecom and ground fault
applications. It is an 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 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.
APPLICATIONS
• General telecom switching
• Instrumentation
• Industrial controls
Note
• See “solid-state relays” (application note 56)
