Overview
LM119J/883/MABI from Texas Instruments is a radiation-hardened, high-speed dual comparator in a 14-pin CDIP package, featuring ±15V or single 5V operation, 80 ns typical response time, 1 μA max input bias current, and uncommitted collector outputs capable of 25 mA sink current. It serves precision analog threshold detection in military avionics and space-qualified power sequencing systems.
For engineers reviewing the LM119J/883/MABI datasheet, LM119J/883/MABI pinout, LM119J/883/MABI application, or LM119J/883/MABI equivalent, this page delivers verified radiation-tolerant comparator specifications, validated pin functions for CDIP-14, real-world use cases in relay driving and window detection, and two qualified alternative part numbers with documented functional trade-offs.
Technical Context
The LM119J/883/MABI implements two independent open-collector comparators on a monolithic die, each with differential inputs and rail-to-rail common-mode range up to ±12V at ±15V supplies. Its architecture supports TTL/DTL/RTL interfacing and direct lamp or relay drive without external pull-ups.
It operates across −55°C to +125°C, meets MIL-STD-883 Class B requirements, and is specified for high-dose-rate (100 krad(Si)) and ELDRS-free radiation environments. Input offset voltage remains ≤±6.8 mV over temperature and supply variations.

Use Value: Independent ground references (pins 3 and 13) allow true differential window sensing without shared return-path errors. |
| Power Sequencing Monitor | Analog Fault Detection |
Use Scenario: Validating correct startup order of multiple DC/DC converters in radar transceiver modules before enabling RF amplifiers. IC Role / Device Role / Timing Role: Each comparator verifies presence and stability of individual supply rails (e.g., +12V, +5V) prior to asserting enable signals. Use Value: 80 ns response time ensures sub-microsecond fault capture, preventing latch-up in downstream FPGAs or ADCs. | Use Scenario: Detecting open-circuit or short-circuit conditions in strain-gauge bridges used in flight control surface position sensors. IC Role / Device Role / Timing Role: Compares bridge output against calibrated high/low thresholds to flag out-of-range mechanical deflection. Use Value: ±12V common-mode input range accommodates full-scale bridge excitation voltages without attenuation or clamping networks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM119JRLQMLV | Same CDIP-14 package, identical electrical specs, but qualified under QML-38534 Class V (not Class B); lower screening rigor for non-mission-critical programs. | Approved for less stringent military ground systems; not rated for space launch vibration or extreme thermal cycling. | Select when radiation tolerance is required but full MIL-STD-883 Class B testing is unnecessary. |
| LM119W/883 | CFP-10 package (10-pin metal can), same radiation spec, but only one comparator per package - requires two units for dual functionality. | Used where hermetic metal-can packaging is mandated for moisture resistance in humid coastal deployments. | Choose when TO-100 mechanical robustness outweighs board space efficiency and dual-channel integration. |
Compared with LM119JRLQMLV, the LM119J/883/MABI offers stricter Class B screening for mission-critical avionics; versus LM119W/883, it delivers dual-channel integration in a single CDIP footprint, reducing PCB area and interconnect complexity.
