Multichannel Optocoupler with Phototransistor Output

Description

The CNY74-2 and CNY74-4 consist of a phototransistor

optically coupled to a gallium arsenide infrared emitting

diode in a 8 lead, resp. 16 lead plastic dual inline pack-

ages.

The elements are mounted on one leadframe in coplanar

technique, providing a fixed distance between input and

output for highest safety requirements.
