The CNY74-2H is a high-speed, high-sensitivity, infrared optocoupler from Vishay. This part is a 6-pin dip, plastic housed optocoupler and consists of a gallium arsenide infrared LED and a high-speed integrated detector. The LED is optically coupled to a photo detector and provides isolation between the input and output. The device is also rated for 1kVrms of input/output isolation. The CNY74-2H is designed for use in digital and analog circuits, such as data communication, and can be used to isolate power, ground, and signal lines.
