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) Parameter Emitter Forward Voltage VF Detector BVCEO BVEBO BVCBO ICEO Package VCEsat DC Current Transfer Ratio IL/D250 IL/D251 IL/D252 Symmetry CTR @ +10 mA 50 20 100 0.50 1.0 2.0 0.4 V % IF= 16 mA, IC=2 mA IF= 10 mA, VCE=10 V 30 7 70 50 10 90 5 50 V V V nA IC=1 mA IE=100 A IC=10 A VCE=10 V 1/2 1.5 V IF= 10 mA Min.
