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 trans-
fer ratio (CTR) minimum of 20 % at IF = 10 mA.
Applications
Telecom applications ring detection
Description
The IL256A is an AC input phototransistor optocou-
pler. The device consists of two infrared emitters con-
nected in reverse parallel and coupled to a silicon
NPN phototransistor detector.
These circuit elements are constructed with a stan-
dard SOIC-8 foot print.

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.
