The NUF2221W1 is a USB upstream terminator designed to provide line termination, EMI filtering, and ESD protection for USB ports. It offers an integrated solution in a compact SC-88/SOT-363 package, reducing PCB space and cost. This device is ideal for upstream USB ports, cellular phones, wireless equipment, and computer applications, ensuring compliance with IEC61000-4-2 (Level 4) ESD standards. Its bi-directional filtering prevents noise from entering or leaving the system, while flexible pull-up line termination meets USB 1.1 Low Speed and High Speed specifications. The integrated circuit enhances system reliability compared to discrete component implementations.
