The HCPL-4502, HCPL-2503, 6N135, 6N136 and HCPL-2530, HCPL-2531 optocouplers
consist 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 480 V working voltage
compared to industry standard 0f 220 V. […]
