Description

 [CT Micro International Corporation]

Description
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.

Features
• Low current – 0.5mA
• Superior CTR-2000%
• CTR guaranteed 0–70°C

Applications
• Digital logic ground isolation
• Telephone ring detector
• EIA-RS-232C line receiver
• High common mode noise line receiver
• μP bus isolation
• Current loop receiver
