Optocoupler, Photodarlington Output, AC Input,
High Gain (Single, Dual Channel)
DESCRIPTION
The IL755, ILD755 are bidirectional input optically coupled
isolators. They consist of two gallium arsenide infrared
emitting diodes coupled to a silicon NPN photodarlington
per channel.
The IL755 is single channel Darlington optocoupler. The
ILD755 has two isolated channels in a single DIP package.
FEATURES
AC or polarity insensitive inputs
Built-in reverse polarity input protection
Industry standard DIP package
Compliant to RoHS Directive 2002/95/EC and
in accordance to WEEE 2002/96/EC
APPLICATIONS
Designed for applications requiring detection or
monitoring of AC signals

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 testing requirements. Typical values are characteristics of the device and are the result of engineering
evaluation. Typical values are for information only and are not part of the testing requirements.
