ONSEMI 6N138M Split Darlington Optocoupler

The ONSEMI 6N138M is a single-channel split darlington optocoupler designed for applications requiring high gain and efficient isolation. Its split darlington configuration enables lower output saturation voltage and faster operation. The device's low input current and high current transfer ratio make it ideal for interfacing with MOS, CMOS, LSTTL, and EIA RS232C circuits. It is commonly used in digital logic ground isolation, telephone ring detection, and micro-processor bus isolation.
