Overview
The LM139JAN is a low-power, low-offset voltage quad comparator manufactured by Texas Instruments. It operates from a single power supply ranging from 5V to 36V DC or split supplies of ±2.5V to ±18V DC. The device features four independent precision comparators with an offset voltage specification as low as 2mV maximum. Key electrical characteristics include a very low supply current drain of 0.8mA, independent of the supply voltage. Input biasing current is specified at 25nA, and input offset current is ±5nA. The input common-mode voltage range includes ground, allowing sensing near GND even with a single supply.
Feature Summary
- Wide supply voltage range supporting single or dual power configurations
- Low power supply current drain independent of supply voltage magnitude
- Input common-mode voltage range includes ground for near-GND sensing
- Output voltage compatible with TTL, DTL, ECL, MOS, and CMOS logic systems
Applications
- Limit comparators
- Simple analog to digital converters
- Pulse, squarewave and time delay generators
- Wide range VCOs
- MOS clock timers
Procurement Notes
Verify that the component matches the specific military-grade designation JM38510/11201BDA. Confirm compliance with Mil-Std-883, Method 5005 Group A quality conformance inspection requirements. Ensure the package type corresponds to the ceramic flat pack (CFP) NAD0014B configuration. Validate that the part marking aligns with the JL139BDA Q identifier found in official documentation.
Selection Notes
Select this component when high precision is required alongside low power consumption. The wide differential input voltage range equal to the power supply voltage allows flexibility in circuit design. The open-collector output facilitates wired-OR connections and compatibility with various logic families. Consider the temperature coefficient specifications if operation across extreme environmental temperatures is necessary.
Part Context
This device belongs to the LM139 family of quad comparators designed specifically for operation from a single power supply over a wide range of voltages. The LM139JAN variant represents the military-grade version of this series, offering enhanced reliability and performance specifications compared to commercial counterparts. It shares functional similarities with other members of the LMx39 family but adheres to stricter manufacturing standards.
Replacement Considerations
JM38510/11201BDA serves as a direct military-grade equivalent to the standard LM139JAN. M38510/11201BDA is also listed as an active production part within the same package configuration. Verify pinout compatibility and ensure that any substitute meets the same Mil-Std-883 quality conformance inspection criteria.
