CNY74-2/CNY74-4
Rev. A1: 19.09.1995 1 (6)
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
output for highest safety requirements.
