Overview
The LM119WGRQMLV 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 and ground. 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 has a typical response time of 80 ns at ±15V supplies.
Feature Summary
- Available with radiation ensured performance
- Two independent comparators on a single chip
- Operates from a single 5V supply
- High common mode slew rate
Applications
- Relay Driver
- Window Detector
Procurement Notes
Verify that the specific ordering suffix matches the required radiation qualification (High Dose Rate or ELDRS Free) and package type (CFP). Confirm military or space qualification status aligns with project requirements. Ensure thermal management meets absolute maximum ratings for power dissipation within the operating temperature range.
Selection Notes
Select this component when high speed and radiation tolerance are critical. Compare against standard commercial comparators if radiation hardness is not required. Consider the open-collector output capability for interfacing with various logic families. Evaluate power dissipation limits relative to ambient temperature and airflow conditions.
Part Context
This part belongs to the LM119QML family of high-speed dual comparators. It is specifically qualified under QML standards for military and defense applications. The device is manufactured by Texas Instruments and is available in ceramic packages suitable for harsh environments.
