Overview
The LM119JRQMLV is a precision 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 and ground. It features higher gain and lower input currents than devices like the LM710. The uncommitted collector output stage makes it compatible with RTL, DTL, and TTL, capable of driving lamps and relays at currents up to 25 mA. Although designed primarily for digital logic supplies, it is fully specified for power supplies up to ±15V. It offers faster response times than the LM111 at the expense of higher power dissipation.
Feature Summary
- Available with radiation ensured performance
- Two independent comparators on a single chip
- Operates from a single 5V supply
- Typically 80 ns response time at ±15V
Applications
- Relay Driver
- Window Detector
Procurement Notes
Verify that the component meets the specific QMLV qualification requirements for your application. Confirm the radiation tolerance specifications, including High Dose Rate and ELDRS Free status, align with your environmental constraints. Ensure the CDIP package type matches your board layout and assembly capabilities. Check for any specific military or space-grade certifications required by your procurement standards.
Selection Notes
Select this component when high-speed comparison is required in radiation-hardened environments. Consider its ability to operate from a single 5V supply if system power constraints exist. Evaluate the trade-off between its faster response time compared to older devices and its higher power dissipation. Ensure the open-collector output interface is compatible with the downstream logic family.
Part Context
This device belongs to the LM119QML family of high-speed dual comparators. It is specifically qualified under the QMLV standard, indicating suitability for military and defense applications. The 'JR' suffix denotes the CDIP (Ceramic Dual In-line Package) form factor. It serves as a robust alternative to commercial comparators in harsh environments requiring radiation tolerance.
