STMicroelectronics 2-Channel General Purpose Comparator Open Collector TTL Output 5-15 V 14-Pin SOIC LM219DT

STMicroelectronics LM219DT is a 2-channel general purpose comparator designed for electronic applications requiring precise and reliable signal comparison. It offers an open collector TTL output type enabling easy interfacing with digital logic circuits. The built-in fast response time of 80 ns ensures suitability for high-speed circuit requirements.

This comparator operates within a supply voltage range of 5 V to 15 V, making it versatile for various power configurations. Packaged in a space-efficient 14-pin SOIC surface mount package, it supports modern high-density PCB layouts. The device dimensions are 8.75 mm in length, 4 mm in width, and 1.65 mm in height, allowing compact integration in electronic assemblies.

Designed for robustness, the LM219DT can reliably function over a wide temperature range from -45°C to 105°C, suitable for industrial and automotive working conditions though it is not certified as automotive grade. Its typical supply current of 11.5 mA enables low power operation while maintaining performance.

The two channels integrated within the package allow for multiple comparator tasks within a single component, simplifying design complexity and reducing PCB space requirements. Open collector TTL output is ideal for interfacing with various logic standards and allows wired-AND connection capability.
