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.
