The Texas Instruments LM339DR is a quad differential comparator integrated circuit housed in a 14-SOIC package, suitable for surface mount applications. This device features four independent comparator elements, each capable of differential input.
Key electrical specifications include an operating temperature range of 0°C to 70°C, a typical supply current of 0.2mA per channel, and a maximum offset voltage of 5mV at 25°C. The output type supports CMOS, MOS, Open-Collector, and TTL logic levels. The comparator operates with a supply voltage ranging from 2V to 30V, and its common-mode input voltage range extends from 0V to 28.5V.
The LM339DR has a propagation delay time of 1.3µs and an input bias current of up to 50nA. Its package is a standard 14-SOIC with a width of 3.90mm. The component is designed for reliable performance in various electronic circuits requiring precise voltage level detection and comparison.
This comparator is a versatile component for signal conditioning, threshold detection, and other logic-level interface applications. Its robust design and standard packaging make it a common choice for industrial and commercial electronic designs.
