LM239N General Description

The LM239N stands out as a reliable solution for voltage comparison tasks, offering precision and efficiency in equal measure. Its low offset voltage of 2 mV for all four comparators ensures minimal errors in comparisons. Operating seamlessly on both single and split power supplies, the LM239N maintains a low current drain regardless of the power supply voltage. Its ability to interface with TTL, CMOS, and MOS logic underscores its compatibility with a wide range of electronic systems
