The HCPL-2631#520 is an optoisolator logic output device containing a HFCT-5611 optocoupler Arduino component and a 500 mA open collector output. It isolates the input and output voltages up to a minimum breakdown voltage of 3 kVrms. The device is commonly used for isolating digital signals like logic levels, relays, and transistors to act as a buffer between two sections of integrated circuits (ICs) with differing operating voltages. It prevents noise and other interference from affecting the connected ICs, and prevents the ICs from interfering with other signals and components. The logic output side combines two optocouplers in an integrated 6-pin package to drive a 500 mA output with 3.75 Volt (V) logic levels. It also features a low power charge injection (<10 nA) and low leakage current (<100 pA). This makes it ideal for isolating low power and low voltage signals, like logic levels and relay circuits. The optocoupler uses an LED and phototransistor to transfer signals across an isolation barrier, eliminating the need for diode clamps or soldered wire connections.The HCPL-2631#520 is frequently utilized in applications involving motors, PLCs, signal transmission, and other applications that require an efficient signal transfer from one point to another. The device offers excellent noise immunity and reliability due to its photosensitive construction, and does not require any external circuitry for operation. It also features a low power dissipation (<100 mW), low temperature drift (<0.1%/°C) and short rise/fall times (<65 ns). As a result, it is suitable for transporting digital signals over extended distances with minimum distortion.In terms of electrical characteristics, the device has an LED forward current of 12-50 mA and a modulation speed of 0.25 µS. Its response time is 250 ns min, and the output is current-limited, with a minimum current-limit of 500 mA at an operating voltage of 4.8V. Its resistor temperature coefficient is also very good with a value of 0.6Ω/°C up to 150°C. In terms of environmental concerns, the device meets the industry standard ESD protection requirements, and is able to operate in temperatures ranging from -40℃ to +85℃.The HCPL-2631#520 is a versatile and cost-effective device that can be used to isolate and transmit digital signals—from low to high-level voltages—over long distances without signal distortion. Due to its low power consumption, high isolation capability, fast run time, and excellent electrical characteristics, the device is highly reliable and perfect for use in harsh environments. It is designed to offer high performance and features a 6-pin, through-hole package for ease of installation in a variety of settings.
