DESCRIPTION

The LH1500 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.
