Low current – 0.5mA 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 common mode noise line receiver Current loop receiver 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.
The devices are packaged in an 8-pin widebody package and also available in surface mount lead forming option.
