LM219DT ST Comparator | 14-SO | Dual, Low Offset, Fast Response

Product Overview

The LM219DT from STMicroelectronics is a high-speed dual voltage comparator designed for applications requiring fast response and low offset voltage. Housed in a compact 14-SO package, it operates over a wide supply voltage range from 5V to 30V (or ±2.5V to ±15V). The device features open-collector outputs, allowing wired-OR connections, and is pin-compatible with the industry-standard LM219. Its typical propagation delay of 80 ns makes it suitable for high-speed signal processing in industrial and automotive systems.
