NE521DR2G

NE521DR2G Description

The NE521DR2G from onsemi is a high-performance dual differential comparator designed for precision signal comparison in TTL-compatible systems. Packaged in a 14-SOIC surface-mount format and supplied in Tape & Reel (TR), it is optimized for automated assembly. Operating within a ±4.75V to ±5.25V dual-supply range, this comparator delivers low input offset voltage (max 7.5mV) and fast propagation delay (max 12ns), making it ideal for high-speed applications. With quiescent current ≤35mA and input bias current ≤20µA, it balances power efficiency with performance. The device is RoHS3 compliant, REACH unaffected, and rated for 0°C to 70°C operation, ensuring reliability in industrial and commercial environments.
