The 4N25/A, 4N26, 4N27 and 4N28 devices consist of a gallium arsenide
infrared emitting diode optically coupled to a monolithic silicon phototransistor
detector.
• Most Economical Optoisolator Choice for Medium Speed, Switching Applications
• 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
• I/O Interfacing
• Solid State Relays

1. Isolation surge voltage is an internal device dielectric breakdown rating.
1. For this test, Pins 1 and 2 are common, and Pins 4, 5 and 6 are common.
2. 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.
