IL221AT/222AT/223AT

Optocoupler, Photodarlington Output,

Low Input Current, High Gain, with Base

Connection

Vishay Semiconductors

Note

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.

Note

Minimum and maximum values are tested requierements. Typical values are characteristics of the device and are the result of engineering

evaluations. Typical values are for information only and are not part of the testing requirements.
