.The OR-1009 with Optocouplers SMD-4 RoHS is a surface-mount, four-channel optocoupler integrated circuit (IC) manufactured by Orient. It features four isolated photocoupler channels with a low input current requirements, and an optical isolation voltage of up to 5000Vrms. The OR-1009 has an industry-standard 8-pin DIP package and is capable of operating in temperatures ranging from -40? to +85?. The device uses light-activated ESIST (electrostatic self-insulated structure) technology, and is compliant with RoHS guidelines for environmental compliance. With its low input current and high isolation voltage, the OR-1009 is the perfect choice for electrical isolation, signal transmission, signal conversion, and hardware-level control.
