CNY74–2H/ CNY74–4H
Vishay Telefunken
Multichannel Optocoupler with Phototransistor Output
Description
The CNY74-2H and CNY74-4H consist of a photo-
transistor optically coupled to a gallium arsenide
infrared-emitting diode in an 8-lead, resp. 16-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
Galvanically separated circuits, non-interacting
switches
