DESCRIPTION
The CNY6XST, the high isolation voltage SMD version optocouplers consist of a phototransistor optically coupled
to a gallium arsenide infrared-emitting diode in a 4 pin plastic package. 
The single components are mounted opposite one another, providing a distance between input and output for highest safety requirements of > 3 mm.
