Description
●These dual channel optocouplers contain a pair of light emitting diodes and integrated photodetectors with electrical insulation between input and output. Separate connection for the photodiode bias and output transistor collectors increase the speed up to a hundred times that of a conventional phototransistor coupler by reducing the base collector capacitance.
