With four separate comparator units, the LM339N is ideal for single power supply setups."

LM339N General Description

With its ability to directly interface with TTL and CMOS, the LMx39-N series offers added flexibility in its applications. Furthermore, when operated from both plus and minus power supplies, these devices can seamlessly interface with MOS logic, with the low power drain of the LM339 providing a distinct advantage over standard comparators. This makes the LM339N an attractive choice for electronic circuits where power efficiency is a key consideration

Key Features

  • The LM339N is a quad voltage comparator with open collector outputs
  • It operates from a single power supply and has low input offset voltage
  • It features wide range of supply voltage, low input bias current, and high input impedance
  • Additionally, it offers TTL, DTL, ECL, MOS, CMOS compatible outputs and can operate in temperature ranges from 0°C to 70°C
  • Application
