Description

The LH1546AEF (4 Pin SOP) is robust, ideal for tele- com and ground fault applications. It is a SPST nor- mally open switch (1 Form A) that replaces electromechanical relays in many applications. It is constructed using a GaAs LED for actuation control and an integrated monolithic die for the switch output. The die, fabricated in a high-voltage dielectrically iso- lated BCDMOS technology, is comprised of a photo- diode array, switch control circuitry and MOSFET switches. In addition, LH1546AEF employs current-limiting cir- cuitry which meets FCC 68.302 and other regulatory voltage surge requirements when overvoltage protec- tion is provided.
