The HCPL-2531 is a dual-channel Output Optocoupler consists of an AlGaAs LED optically coupled to a high speed photodetector transistor. A separate connection for the bias of the photodiode improves the speed by several orders of magnitude over conventional phototransistor optocoupler by reducing the base-collector capacitance of the input transistor.
