LM339ADBR TI Comparator IC | 14-SSOP | Low Power, Open Collector Output

Product Overview

The LM339ADBR is a quad differential comparator from Texas Instruments, designed for low-power voltage comparison applications. It features open-collector outputs, wide supply voltage range (2V to 36V), and low supply current (0.8 mA typical). Housed in a compact 14-SSOP package, it is ideal for space-constrained designs requiring multiple comparators.
