NTE3044
Optoisolator
NPN Darlington Transistor Output
Description:
The NTE3044 consists of a gallium arsenide infrared emitting diode optically coupled to a monolithic
silicon photodarlington detector in an 6–Lead DIP type package. This device is designed for use in
applications requiring high sensitivity at a low input current.
