CT Micro 6N138
The 6N138 & 6N139 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 DIP package and also available in gullwing (400mil) spacing and surface mount lead forming option.| Part No. | 6N138 |

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 recommended operating conditions may affect device reliability.
