  • CNY74-4 IC - 4-Channel Optocoupler with Phototransistor IC

The CNY74-4 consist of a photo transistor 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 highest safety requirements. 


• CNY74-4 includes 4 isolator channels 

DC isolation test voltage VIO = 2.5 kV 

Test class 25/100/21 DIN 40 045 

Low coupling capacitance of typical 0.3 pF 

Current Transfer Ratio (CTR) of typical 100% 

Low temperature coefficient of CTR 

Wide ambient temperature range

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