Optocoupler, Phototransistor Output, AC Input,
with Base Connection
DESCRIPTION
The IL250, IL251, IL252, ILD250, ILD251, ILD252 are
bidirectional input optically coupled isolators consisting of
two gallium arsenide infrared LEDs coupled to a silicon NPN
phototransistor per channel.
The IL250, ILD250 has a minimum CTR of 50 %, the IL251,
ILD251 has a minimum CTR of 20 %, and the IL252, ILD252
has a minimum CTR of 100 %.
The IL250, IL251, IL252 are single channel optocouplers.
The ILD250, ILD251, ILD252 has two isolated channels in a
single DIP package.
FEATURES
• AC or polarity insensitive inputs
• Built-in reverse polarity input protection
• Improved CTR symmetry
• Industry standard DIP package
• Compliant to RoHS Directive 2002/95/EC and
in accordance to WEEE 2002/96/EC
APPLICATIONS

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.
