HCPL2531SV Datasheet

High Speed Optocouplers


The HCPL2531SV 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 480V working voltage compared to industry standard of 220V. HCPL2531SV Features • High speed –1 MBit/s• Superior CMR – 10kV/µs• Dual-Channel HCPL2530/HCPL2531• Double working voltage – 480V RMS• CTR guaranteed 0–70°C• U.L. recognized (File # E90700) HCPL2531SV Applications • Line receivers • Pulse transformer replacement• Output interface to CMOS-LSTTL-TTL• Wide bandwidth analog coupling
