Model LM139AJ
Description LMx39/LM2901 The series of four-way comparators Texas Instruments LM139, LM239, LM339, and LM2901 are all four-way differential input voltage comparators designed to operate from a single power source with various voltages. The common mode input voltage series includes grounding, and the device has an open collector output. ###The Texas Instruments series voltage comparator includes not only traditional single, dual, and four-way comparator packages, but also window comparators and overvoltage and undervoltage monitors. Although comparators and operational amplifiers appear to be similar devices, their operations in practical applications are significantly different. Operational amplifiers are suitable for linear operation with appropriate feedback, while comparators are customized for fast switching and typically operate in open circuit mode. The dedicated voltage comparator has a significantly shorter propagation delay and can have a faster response time under saturation conditions. Most comparators are also more tolerant of high differential input voltages, and many comparators have open collector outputs, allowing them to operate in parallel with other devices.
