CT Micro CTW138
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.| Part No. | CTW138 |
