6N137 High Speed Optocoupler IC

Isolate and protect your circuits without sacrificing signal speed using the 6N137 High Speed Optocoupler, a single-channel logic gate optocoupler built around an 850nm infrared LED optically coupled to an integrated high-speed photodetector. Housed in an 8-pin DIP package, it electrically isolates two circuits while still passing digital signals at up to 10 Mbit/s, making it a dependable choice wherever noise immunity and safety isolation matter as much as switching speed. The open-drain NMOS output offers lower leakage than older Schottky-clamped transistor designs, and a dedicated strobe/enable pin lets you gate the output on demand, useful for building precise strobe or timing circuits. With a typical propagation delay in the tens of nanoseconds and strong common-mode transient immunity, the 6N137 handles clean, reliable data transfer even in electrically noisy environments. It’s a popular pick for hobbyists and engineers building line receivers, isolated feedback loops in switch-mode power supplies, ground-isolated logic interfaces, and general digital noise elimination between microcontroller and high-voltage sections of a circuit. Because it runs on a standard 5V logic supply and is LVTTL/LVCMOS compatible, it drops easily into most digital and microcontroller-based designs, giving your project robust electrical isolation without adding complexity to the signal path.
