Description
The IL755/ ILD755 are bidirectional input optically
coupled isolators. They consist of two Gallium Ars-
enide infrared emitting diodes coupled to a silicon

Absolute Maximum Ratings
T
amb
= 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.
