NTE NTE3044 Datasheet

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.

Features:

D High Sensitivity to Low Input Drive Current
D High Collector–Emitter Breakdown Voltage
D No Base Conncetion for Improved Noise Immunity

Applications:

D Appliances, Measuring Instruments
D I/O Interfaces for Computers
D Programmable Controllers
D Portable Electronics
D Interfacing and Coupling Systems of Different Potentials and Impedances
D Solid State Relays

Absolute Maximum Ratings:

(TA = +25°C unless otherwise specified)
