LM339N Description

Short technical summary and product information.

The STMicroelectronics LM339N is a versatile quad general purpose comparator suitable for various consumer, automotive, and industrial electronic applications. It supports single supply operation from 3.0 V to 36 V and split supply operation from ±1.5 V to ±18 V. Key electrical characteristics include a low input bias current of 25 nA (Typ) and a low input offset current of ±5.0 nA (Typ). The device features an input common mode voltage range to GND and a low output saturation voltage of 130 mV (Typ) at 4.0 mA.

 

This comparator is compatible with TTL and CMOS logic levels. It is available in a 14-DIP Through Hole package, making it suitable for breadboarding and through-hole PCB assembly. The operating temperature range is 0°C to 70°C, and it is RoHS3 Compliant, Pb-Free, and Halogen Free.

 

Applications include level detection, low-level sensing, and memory applications where precise voltage comparisons are required. The open-collector output type allows for flexible interfacing with different logic families.
