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.
Features:-
• 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:-Â Galvanically separated circuits, non-interacting switches.
