LM139DR TI Comparator | 14-SOIC | Quad, Low Power, Open Collector Output

Product Overview

The LM139DR from Texas Instruments is a quad differential comparator designed for low-power applications. It operates from a single power supply over a wide voltage range of 2V to 36V (or ±1V to ±18V for dual supplies). The device features open-collector outputs, allowing wired-AND connections. It is offered in a 14-pin SOIC package, making it suitable for space-constrained designs.

Detailed Technical Specifications

Key Features

• Quad comparators in a single package
