Description  

The ELM452 and ELM453 devices each consist of an infrared emitting diode, optically coupled to a high speed photo detector transistor. A separate connection for the photodiode bias and output-transistor collector increase the speed by several orders of magnitude over conventional phototransistor couplers by reducing the base-collector capacitance of the input transistor. The devices are packaged in industry standard 5pin SOP packages and are suitable for surface mounting. 

Applications 

• Line receivers

 • Field bus communication and control. 

• Power transistor isolation in motor drives 

• Replacement for low speed phototransistor photo couplers

 • High speed logic ground isolation 

• Analog signal ground isolation
