Product Summary

The CNY74-4H is a Multichannel Optocoupler. It consists of a phototransistor optically coupled to a gallium arsenide infrared emitting diode in a 8 lead, resp. 16 lead plastic dual inline packages. The elements are mounted on one leadframe in coplanar technique, providing a fixed distance between input and output for highest safety requirements. The applications of the CNY74-4H are aalvanically separated circuits, non-interacting switches.
