Motorola Optoelectronics Device Data

6-Pin DIP Optoisolators

Transistor Output

The 4N38 and 4N38A(1) devices consist of a gallium arsenide infrared

emitting diode optically coupled to a monolithic silicon phototransistor detector.

• Guaranteed 80 Volt Collector–to–Emitter Breakdown ((BR)CEO)) Minimum

• Meets or Exceeds All JEDEC Registered Specifications

• To order devices that are tested and marked per VDE 0884 requirements, the

suffix ”V” must be included at end of part number. VDE 0884 is a test option.

Applications

• General Purpose Switching Circuits

• Interfacing and coupling systems of different potentials and impedances

• Monitor and Detection Circuits

1. 4N38 does not require UL approval; 4N38A does. Otherwise both parts are identical. Both parts

2. Isolation surge voltage is an internal device dielectric breakdown rating.

3. Refer to Quality and Reliability Section in Opto Data Book for information on test conditions.

Preferred devices are Motorola recommended choices for future use and best overall value.
