DESCRIPTION

The LH1546 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 GaAlAs LED for actuation control

and MOSFET switches for the output. In addition, it employs

current-limiting circuitry to provide overvoltage protection.
