Part Number: ELM453(TA)-V

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.
