Description
The IL255 is a bidirectional input optically coupled
isolator consisting of two high current GaAs infrared
LEDs coupled to a silicon NPN phototransistor. The
IL255 has a minimum CTR of 20 %
This optocoupler is ideal for applications requiring AC
signal detection and monitoring.
Order Information
For additional information on the available options refer to
Option Information.
Absolute Maximum Ratings
Tamb = 25 °C, unless otherwise specified
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 Rating for extended periods of the time can adversely affect reliability.
