CNY75(G) Series
Vishay
Semiconductors
Optocoupler with Phototransistor Output
Description
The CNY75(G) series consists of a phototransistor
optically coupled to a gallium arsenide infrared-
emitting diode in a 6-lead plastic dual inline package.
The elements are mounted on one leadframe using
a
coplanar technique,
providing a fixed distance
between input and output for highest safety
requirements.
Applications
