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.
