Product details
Overview
LM119H/NOPB from Texas Instruments is a precision high-speed dual comparator IC designed for aerospace, military, and industrial applications requiring operation across −55°C to +125°C. It features two independent comparators, 80-ns typical response time at ±15 V, uncommitted open-collector outputs capable of sinking up to 25 mA, and operates from a single 5-V supply or dual ±15-V supplies. Its inputs and outputs are isolated from system ground, enabling flexible interfacing in relay driver and window detection circuits.
For engineers reviewing the LM119H/NOPB datasheet, LM119H/NOPB pinout, LM119H/NOPB application, or LM119H/NOPB equivalent, this page delivers verified technical context, package-specific pin functions, real-world use cases, and validated alternative options - all grounded in TI's production-grade SNOSBJ2B specification and orderable packaging data.
Technical Context
The LM119H/NOPB implements two fully independent voltage comparators on a single monolithic die, each with high-gain differential input stages and uncommitted NPN output transistors. Its architecture supports TTL/DTL/RTL compatibility via external pull-up resistors and enables direct driving of relays or lamps without additional interface circuitry.
It features high common-mode slew rate and input voltage range extending to ±13 V under ±15-V supplies, with guaranteed operation down to a single 5-V logic supply. The device's −55°C to +125°C temperature rating and TO-100 metal-can package reflect its qualification for high-reliability environments where thermal stability and hermetic sealing are critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM219H/NOPB | Same TO-100 package and pinout; rated for −25°C to +85°C instead of −55°C to +125°C. | Not suitable for extended-temperature military/aerospace deployments; acceptable for commercial industrial controls. | Select LM219H/NOPB only if full military temperature range is unnecessary and cost optimization is prioritized. |
| LM319AM/NOPB | SOIC-14 surface-mount package; 0°C to +70°C rating; improved offset voltage (1 mV typ) but slower 100-ns response. | Designed for cost-sensitive consumer/industrial PCBs; lacks hermetic sealing and extended thermal performance. | Choose LM319AM/NOPB for automated assembly and volume production where environmental ruggedness is secondary. |
Compared with LM219H/NOPB and LM319AM/NOPB, the LM119H/NOPB uniquely combines military-grade temperature range, TO-100 hermetic reliability, and 80-ns speed - making it irreplaceable in safety-critical embedded systems where thermal margin and long-term stability are non-negotiable.

FAQ
What is the maximum supply voltage for LM119H/NOPB?
The LM119H/NOPB supports a total supply voltage up to 36 V, with absolute maximum ratings specifying ±15 V for dual supplies or 5 V for single-supply operation. Operation above 16 V between ground and either supply rail is prohibited per TI's SNOSBJ2B datasheet, and the device must not be subjected to differential input voltages exceeding ±5 V.
Does LM119H/NOPB have internal pull-up resistors on its outputs?
No, the LM119H/NOPB does not include internal pull-up resistors. Its outputs are uncommitted open-collector NPN transistors that require external pull-up resistors to define logic-high voltage levels. This architecture enables flexible interfacing with TTL, DTL, RTL, or custom voltage rails, and allows wired-OR configurations across multiple comparators.
Can LM119H/NOPB operate from a single 5-V supply?
Yes, the LM119H/NOPB is explicitly specified to operate from a single 5-V supply with ground reference. Electrical characteristics including input offset voltage, response time, and output saturation voltage are validated under this condition, and the device maintains full functionality across its −55°C to +125°C temperature range even at 5-V operation.
What is the thermal resistance of LM119H/NOPB in its TO-100 package?
The LM119H/NOPB in the TO-100 (LME) package has a junction-to-ambient thermal resistance (RθJA) of 160°C/W and a junction-to-case (top) thermal resistance (RθJC(top)) of 19°C/W, as documented in TI's SNOSBJ2B datasheet Section 5.3. These values apply to the hermetically sealed metal-can construction and inform derating requirements for continuous power dissipation.
Is LM119H/NOPB RoHS compliant?
Yes, LM119H/NOPB is RoHS compliant, as confirmed in TI's official packaging addendum: "RoHS: Yes" for orderable part number LM119H/NOPB. It uses lead-free finish and meets EU Directive 2011/65/EU requirements, with MSL rating Level-1-NA-UNLIM and no exemptions applied.
