The LH1518 relays are capable of switching AC or DC loads from as little as nanovolts to hundreds of volts. The relays can switch currents in the range of nanoamps to hundreds of milliamps. The MOSFET switches are ideal for small signal switching and are primarily suited for DC or audio frequency applications. The LH1518 relays feature a monolithic output die that minimizes wire bonds and permits easy integration of high-performance circuits such as current limiting in normally-open switches. The output die integrates the photodiode receptor array, turn-on and turn-off control circuitry, and the MOSFET switches. The optically-coupled input is controlled by a highly efficient GaAlAs infrared LED. • General telecom switching • Instrumentation • Industrial controls AGENCY APPROVALS UL1577: CSA: BSI: DIN EN: FIMKO: file no.
