DESCRIPTION
The ILD256T is a dual channel optocoupler. Each
channel consists of two infrared emitters coupled to a
silicon NPN phototransistor detector.
These circuit elements are constructed with a standard
SOIC-8A footprint.
The product is well suited for telecom applications
such as ring detection or off/on hook status, given its
bidirectional LED input and guaranteed current
transfer ratio (CTR) of 20 % at I
F
= 10 mA.
AGENCY APPROVALS
• UL1577, File No. E52744 System Code Y
• DIN EN 60747-5-2 (VDE0884)
Available with Option 1
APPLICATIONS
• Telecom applications ring detection off/on hook
status
Note:
For additional information on the available options refer to Option Information.

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.

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.
Note:
1)
As per IEC60747-5-2, §7.4.3.8.1, this optocoupler is suitable for “safe electrical insulation” only within the safety ratings. Compliance with the
safety ratings shall be ensured by means of prodective circuits.
