What the 6N137 family does
The 6N137, EL2601, and EL2611 are high-speed 10 Mbit/s logic gate photocopplers featuring an infrared emitting diode optically coupled to a photo detector with a strobable output. These components operate with a 5000 V rms isolation voltage, handle 50 mA forward current, and function across a -40 to +85°C temperature range. The 8-pin DIP package supports wide-lead spacing and SMD options. Engineers typically use these parts for ground loop elimination, data transmission, line receiving, and switching power supply applications. They also serve as pulse transformer replacements and provide high-speed logic ground isolation in computer peripheral interfaces.
