The Texas Instruments LM139D is a quad differential comparator integrated circuit housed in a 14-SOIC package. This device is designed for applications requiring precise voltage comparisons. It features four independent comparator elements, each with an open-collector output compatible with TTL, MOS, and CMOS logic levels.
The LM139D operates from a supply voltage range of 2V to 36V and maintains functionality across an extended temperature range of -55°C to 125°C. Key electrical characteristics include a typical quiescent current of 0.2mA per channel and a propagation delay of 1.3µs. The input bias current is specified at a maximum of 25nA, and the common-mode input voltage range extends from 0V to 34.5V.
This comparator is suitable for surface mount applications. Its robust design and wide operating parameters make it a versatile choice for various electronic systems where reliable signal level detection is critical. The 14-SOIC package is standard for many through-hole and surface-mount designs, offering a balance of component density and ease of assembly.
