Description
The ELW135, ELW136 and ELW4503 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 an 8-pin DIP wide body package and available in wide-lead spacing and SMD option.
