Overview
The LM119H/883 is a high-speed dual comparator manufactured by Texas Instruments, designed for operation over a wide range of supply voltages down to a single 5V logic supply. It features two independent comparators on a single monolithic chip with higher gain and lower input currents than 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
- High-speed response time typically 80 ns at ±15V
- Uncommitted collector output compatible with multiple logic families
- Low input bias current of maximum 1 μA over temperature
- Capable of driving lamps and relays at currents up to 25 mA
Applications
- Relay Driver circuits
- Window Detector applications
- Digital Logic Power Supply Monitoring
Procurement Notes
Verify that the specific procurement lot matches the required radiation qualification (High Dose Rate or ELDRS Free) as electrical characteristics and post-radiation limits vary between these versions. Confirm the package type corresponds to the TO-100 (LME) outline provided in the datasheet. Ensure handling procedures account for limited built-in ESD protection by using conductive foam or shorting leads during storage.
Selection Notes
Select this component when fast response times are critical compared to older comparators like the LM111. Choose the High Dose Rate version for environments requiring resistance to total ionizing dose up to 100 krad(Si). Select the ELDRS Free variant if enhanced low-dose-rate sensitivity is a concern in space applications. Verify that the single-ended output configuration meets the system's fan-out requirements.
Part Context
This device belongs to the LM119 family of precision high-speed dual comparators. It is an upgraded alternative to the LM711, offering faster response and wider operating voltage ranges in a low package count. The /883 suffix indicates compliance with MIL-STD-883 standards, making it suitable for military and aerospace applications where radiation hardness and reliability are mandated.
