High speed photo coupler NQUNXIN QX6N137-CuH-D designed for ground loop elimination and data transmission in circuits
High Speed Photo Coupler QX6N137
The QX6N137 optocoupler features a high-speed integrated photo-detector logic gate coupled to an 850nm AlGaAS LED, enabling rapid output. It offers a high bit rate of 10Mbit/s, high input-output isolation voltage (5000 Vrms), and operates within a wide temperature range of -40C to +85C. Designed with a logic gate output and strobable functionality, it meets reinforced insulation standards and safety certifications including UL 1577, VDE DIN EN60747-5-5, and CQC11-471543-2022. This device is ideal for applications such as ground loop elimination, LSTTL to TTL/5V CMOS conversion, data transmission, switching power supplies, and computer-peripheral interfaces.
