Overview
The LM119J/883 is a high-speed dual comparator fabricated on a single monolithic chip, designed for operation over a wide supply voltage range down to a single 5V logic supply. It features uncommitted collector outputs compatible with RTL, DTL, and TTL, capable of driving loads up to 25 mA. The device offers a typical response time of 80 ns at ±15V, a maximum input current of 1 μA across the temperature range, and a minimum fan-out of 2 per side. It operates from -55°C to 125°C.
Feature Summary
- Two independent comparators with uncommitted collector outputs
- Compatible with RTL, DTL, and TTL logic families
- Capable of driving lamps and relays at currents up to 25 mA
- Inputs and outputs can be isolated from system ground
Applications
- Relay driver circuits
- Window detector applications
- Digital logic power supply monitoring
Procurement Notes
Verify that the specific procurement order explicitly references the LM119J/883 designation to ensure correct identification. Confirm compliance with required quality conformance inspection standards, such as MIL-STD-883, if applicable to the intended deployment environment. Ensure all handling procedures account for electrostatic discharge protection during storage and installation.
Selection Notes
Select this component when high-speed comparison is required alongside compatibility with standard transistor-transistor logic interfaces. It serves as a versatile alternative to older devices like the LM711, offering faster response times and lower package counts. Consider its higher power dissipation relative to slower comparators when evaluating thermal constraints in the design.
Part Context
This part belongs to the LM119 family of precision high-speed dual comparators manufactured by Texas Instruments. The /883 suffix indicates qualification to military standards, ensuring reliability for demanding environments. It shares functional similarities with the LM119QML but is distinguished by its specific packaging and certification requirements.
