Overview
The LM119WRQMLV is a high-speed dual comparator fabricated on a single monolithic chip, designed for operation over a wide range of supply voltages down to a single 5V logic supply. It features higher gain and lower input currents compared to devices like the LM710. The uncommitted collector output stage allows compatibility with RTL, DTL, and TTL logic families, capable of driving loads such as lamps and relays at currents up to 25 mA. It operates from a single 5V supply or dual supplies up to ±15V.
Feature Summary
- Radiation ensured with High Dose Rate tolerance of 100 krad(Si) and ELDRS Free capability
- Contains two independent comparators on a single chip
- Uncommitted collector output compatible with RTL, DTL, and TTL logic standards
- 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 ordering suffix matches the required radiation qualification (High Dose Rate vs. ELDRS Free). Confirm the package type corresponds to the NAD CFP variant indicated by the WR designation. Ensure the procurement channel provides traceability documentation consistent with QML certification requirements for defense or space applications.
Selection Notes
Select this component when radiation hardness is mandatory for the application environment. Choose between High Dose Rate and ELDRS Free variants based on the specific orbital or nuclear exposure profile. Verify that the ceramic packaging meets the mechanical stress requirements of the target deployment. Compare performance against standard commercial comparators if radiation tolerance is not required.
Part Context
This device belongs to the LM119QML family, which includes various radiation-tolerant versions certified for military and space use. It serves as a robust alternative to commercial comparators in harsh environments. The family offers different radiation hardening options and package styles to suit diverse mission profiles requiring high reliability and speed.
