DESCRIPTION
Switch mode power supply feedback
The 4N25 family is an industry standard single channel
Telephone ring detection
phototransistor coupler. This family includes the 4N25,
Logic ground isolation
4N26, 4N27, 4N28. Each optocoupler consists of gallium
Logic coupling with high frequency noise rejection
arsenide infrared LED and a silicon NPN phototransistor.

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not
implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute
maximum ratings for extended periods of the time can adversely affect reliability.
