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.
