The LM239DR from Texas Instruments is a quad differential comparator designed for various electronic applications. This device features four independent comparator elements, each capable of operating with a supply voltage ranging from 2V to 36V.
The comparator offers an open-collector output type, compatible with TTL, MOS, and CMOS logic levels. It has a typical propagation delay of 1.3µs and a low quiescent current of 0.2mA per channel. The operating temperature range is specified from -25°C to 85°C, making it suitable for commercial grade applications.
Packaged in a 14-SOIC format, the LM239DR is designed for surface mount applications. Its input bias current is a maximum of 250nA, with an offset voltage of 5mV at 25°C. The common-mode input voltage range includes ground, and the differential input voltage range can extend up to the maximum-rated supply voltage of ±38V.
This component is part of the broader LM239 family, known for its reliability and performance in comparison circuits. The LM239DR is a widely used solution for threshold detection, voltage monitoring, and other signal conditioning tasks.
