Overview
The LM139J/883 is a quad differential comparator manufactured by Texas Instruments, designed for military and high-reliability applications. It features four independent voltage comparators in a single package. The device operates with a supply voltage range from 2 V to 36 V. Key electrical parameters include a maximum input offset voltage of 5 mV and an input bias current of 25 nA. The response time is specified at 1300 ns. It supports an operating temperature range from -55 °C to +125 °C. The component utilizes a ceramic dual flatpack (DFP) package with 14 pins.
Feature Summary
- Quad differential comparator architecture providing four independent comparison channels
- Military-grade reliability with ceramic glass-sealed packaging
- Low power consumption suitable for battery-operated systems
- Wide single-supply or split-supply voltage operation capability
Applications
- Military avionics and defense electronics
- High-reliability industrial control systems
- Spacecraft instrumentation and monitoring
- Precision voltage threshold detection circuits
Procurement Notes
Verify the specific suffix J/883 indicates MIL-PRF-38534 compliance when sourcing. Confirm RoHS status as military ceramics often contain lead. Ensure the supplier provides full traceability documentation. Check for updated datasheets from Texas Instruments regarding this legacy part number. Validate package dimensions against your ECAD library before integration.
Selection Notes
Select this component when military qualification and long-term stability are required. Compare response times and offset voltages against standard commercial equivalents like the LM139DR if cost is a primary constraint. Consider the DFP package size constraints during PCB layout. Verify that the 1300 ns response time meets your system speed requirements.
Part Context
The LM139 series is a legacy line of low-power quad comparators originally developed by National Semiconductor and now maintained by Texas Instruments. The J/883 designation specifically denotes a military-grade version packaged in a hermetic ceramic dual flatpack. This variant is distinct from commercial plastic packages like SOIC or DIP, offering superior environmental resistance for harsh operating conditions.
