HCPL2530, покупаем в интернете - получаем у себя дома.

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 the industry standard of 220V.

• 480V RMS Double working voltage
• CTR guaranteed over 0 to 70°C temperature range
