The IL/ILD250 has a minimum CTR of 50%, the IL/ILD251 has a minimum CTR of 20%, and the IL/ILD252 has a minimum CTR of 100%. The IL/IL250/1/2 are single channel optocouplers. The ILD250/1/2 has two isolated channels in a single DIP package. These optocouplers are ideal for applications requiring AC signal detection and monitoring. 5–1 This document was created with FrameMaker 4.0.4 Electrical Characteristics (TA=25 C) Min. Typ. Max .
