Overview
The LM339PWRE4 is a quad differential comparator from Texas Instruments, part of the next-generation LM339B family. These comparators are designed to offer improved specifications over their predecessors, including lower offset voltage, higher supply voltage capability, lower supply current, and lower input bias current. The LM339B devices are drop-in replacements for the LM239, LM339, and LM2901, making them versatile for various applications. Each device consists of four independent voltage comparators that can operate from a single power supply over a wide range of voltages.
