Description
The HCPL-4502/HCPL-2503, 6N135/6 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 rejec-
tion of 10kV/μs. An improved package allows superior insulation
permitting a 480 V working voltage compared to industry stan-
dard of 220 V.
