CTW138 Datasheet | CT Micro

Features Description - Low current - 0.5m A - Superior CTR-2000% - CTR guaranteed 0- 70°C - MSL class 1 - Regulatory Approvals - UL - UL1577 (E364000) - VDE - EN60747-5-5(VDE0884-5) - CQC - GB4943.1, GB8898(19001231774) - IEC62368 (FI/41119) Applications - Digital logic ground isolation - Telephone ring detector - EIA-RS-232C line receiver - High mon mode noise line receiver - Current loop receiver The CTW138 & CTW139 optocouplers consist of an Al Ga As LED optically coupled to a high gain split darlington photodetector. The bination of a very low input current of 0.5m A and a high current transfer ratio of 2000% makes this family particularly useful for input interface to MOS, CMOS, LSTTL and EIA RS232C, while output patibility is ensured to CMOS as well as high fan-out TTL requirements. The devices are packaged in an 8-pin widebody package and also available in surface mount lead forming option. Package Outline Schematic Note: Different lead forming options available.

CTW138, CTW139 Low Input Current Photodarlington Coupler Absolute Maximum Ratings TA = 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. In addition, extended exposure to stresses above the remended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.
