CNY74–2H/ CNY74–4H

Vishay Telefunken

Rev. A2, 19–Jul–99 1 (9)

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 be-

tween input and output for highest safety

requirements.

Applications

Galvanically separated circuits, non-interacting

switches
