CQY80N(G)
Vishay Telefunken
Optocoupler with Phototransistor Output
Description
The CQY80N(G) series consist 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
Circuits for safe protective separation against electri-
cal shock according to safety class II (reinforced
isolation):
14827
