CNY74-2/CNY74-4
Multichannel Optocoupler with Phototransistor Output
Description
The CNY74-2 and CNY74-4 consist 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.
Applications
Galvanically separated circuits, non-interacting switches.
