DESCRIPTION

The LH1546AEF (4 pin SOP) is robust, ideal for telecom and

ground fault applications. It is an 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 MOSFETs for the switch output. In

addition, it employs current-limiting circuitry to provide

overvoltage protection.
