Overview
The LM119QML 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 higher gain and lower input currents compared to devices like the LM710. The device includes two independent comparators with uncommitted collector outputs compatible with RTL, DTL, and TTL. It operates from a single 5V supply or up to ±15V, offering a typical response time of 80 ns at ±15V. The part supports a minimum fan-out of 2 per side and maintains a maximum input current of 1 μA over temperature.
Feature Summary
- Radiation ensured with High Dose Rate tolerance of 100 krad(Si) and ELDRS Free capability
- Two independent comparators with uncommitted collector outputs for broad logic compatibility
- Operates from a single 5V supply or dual supplies up to ±15V
- High common mode slew rate with inputs and outputs isolatable from system ground
Applications
- Digital logic power supply monitoring
- Relay driver circuits
- Window detector applications
Procurement Notes
Verify the specific radiation qualification (High Dose Rate vs. ELDRS Free) required for your application when ordering. Confirm the package type matches your design, as the LM119QML is available in CDIP, LCCC, TO-100, and CFP configurations. Ensure that the selected variant meets the necessary MIL-STD-883 Group 5 inspection requirements for military or space-grade deployments.
Selection Notes
Select the LM119QML when high speed and radiation hardness are critical. Compare against standard LM119 variants if radiation tolerance is not needed. Consider the output saturation voltage and drive current capabilities when interfacing with loads like lamps or relays. Verify thermal resistance values for the chosen package to ensure adequate heat dissipation under operating conditions.
Part Context
The LM119QML is a qualified version of the LM119 series, specifically designed for military and space applications. It offers faster response times than the LM111 while maintaining a versatile operating voltage range. The QML designation indicates compliance with Quality Management Level standards, ensuring reliability in harsh environments through rigorous testing and screening procedures defined by military specifications.
