FAQs

What is LM139AJ/883?

The LM139AJ/883 is a high-performance quad voltage comparator designed by Texas Instruments. It is a rugged military-grade component that operates over a wide temperature range and is suitable for harsh environments and critical applications.

How Does LM139AJ/883 Work?

The LM139AJ/883 functions as a voltage comparator, comparing the voltages on its four input pins and providing a high or low output based on the comparison result. It is used in applications requiring precise voltage level detection, such as threshold detection, window comparators, and voltage monitoring circuits.

How Many Pins does LM139AJ/883 have and What are the Functions of the Pinout Configuration?

The LM139AJ/883 is housed in a 14-pin ceramic DIP (Dual Inline Package) package. The pinout configuration includes:

VCC+: Positive power supply pin.
VCC-: Negative power supply pin.
IN+ and IN- (x4): Non-inverting and inverting input pins for each comparator (quad comparator).
OUT (x4): Output pins for each comparator.
GND: Ground pin.

What are the Pros and Cons of LM139AJ/883?

Pros:

High Reliability: Designed for rugged military applications, ensuring high reliability.
Wide Temperature Range: Operates over a wide temperature range, suitable for extreme environments.
Quad Comparator: Includes four independent comparators in a single package, offering versatility.
Low Input Offset Voltage: Provides accurate voltage comparisons for precise applications.
Robust Construction: The ceramic DIP package provides durability and protection.

Cons:

Size: The 14-pin DIP package may be relatively larger compared to modern surface-mount components.
Power Consumption: May have higher power consumption compared to newer low-power comparator alternatives.
Cost: Military-grade components like the LM139AJ/883 may have a higher cost compared to commercial-grade alternatives.

Are There Any Equivalents/Alternatives to LM139AJ/883 for Recommendation?

The LM339 from Texas Instruments is a similar quad voltage comparator that is widely used in commercial applications.
Alternatives to the LM139AJ/883 include the LM2901 from Texas Instruments and the LM311 from Texas Instruments.
