CTW138, CTW139 Low Input Current Photodarlington Coupler Features • Low current – 0.5mA • Superior CTR-2000% • CTR guaranteed 0–70°C • Regulatory Approvals UL - UL1577 (E364000) VDE - EN60747-5-5(VDE0884-5) CQC – GB4943.1, GB8898 IEC60065, IEC60950 Description The CTW138 & CTW139 optocouplers consist of an AlGaAs LED optically coupled to a high gain split darlington photodetector. The combination of a very low input current of 0.5mA 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 compatibility is ensured to CMOS as well as high fan-out TTL requirements. Applications The devices are packaged in an 8-pin widebody • Digital logic ground isolation package and also available in surface mount lead • Telephone ring detector forming option. • EIA-RS-232C line receiver • High common mode noise line receiver • Current loop receiver Package Outline Schematic CTW138 / CTW139 Note: Different lead forming options available.
