The CNY74-4 consists of a phototransistor optically coupled to a gallium arsenide infrared-emitting diode in an 8-lead, resp. 16-lead plastic dual inline package. The elements are mounted on one lead frame using a co-planar technique, providing a fixed distance between input and output for the highest safety requirements.

Applications:-?Galvanically separated circuits, non-interacting switches.

Features:

1. CNY74-4 includes 4 isolator channels
2. DC isolation test voltage VIO = 2.5 kV
3. Test class 25/100/21 DIN 40 045
4. Low coupling capacitance of typical 0.3 pF
5. Current Transfer Ratio (CTR) of typical 100%
6. Low-temperature coefficient of CTR
7. Wide ambient temperature range
