LM339PW TI Comparator | 14-TSSOP | Quad, Low Power, 2V to 30V

Product Overview

The LM339PW 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 30V, or dual supplies of ±1V to ±15V. The device features low supply current (0.8 mA typical) and open-collector outputs that can interface with various logic families. Housed in a compact 14-TSSOP package, the LM339PW is ideal for space-constrained designs requiring multiple comparators.
