Description

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

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.
