The HCPL-2530 is a 2-channel 1Mbps high-speed Transistor 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 optocouplers by reducing the base-collector capacitance of the input transistor. An internal noise shield provides superior common mode rejection of 10kV/μs. An improved package allows superior insulation permitting a 480V working voltage compared to industry standard of 220V.
