Description
The IL250/ 251/ 252/ ILD250/ 251/ 252 are bidirec-
tional input optically coupled isolators consisting of
two Gallium Arsenide infrared LEDs coupled to a sili-
con NPN phototransistor per channel.
The IL250/ ILD/250 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 optocou-
plers. The ILD250/ ILD251/ ILD252 has two isolated
channels in a single DIP package.
Order Information
For additional information on the available options refer to

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.
