Motorola Optoelectronics Device Data
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
