Overview
The LM119 MDE is a high-speed dual comparator manufactured by Texas Instruments, available as a die sale. It operates from a single 5V logic supply or dual supplies up to ±15V. The device features two independent comparators with an uncommitted collector output capable of driving loads up to 25 mA. Key electrical characteristics include a typical response time of 80 ns at ±15V, a maximum input current of 1 µA over the temperature range, and a minimum fan-out of 2 per side.
Feature Summary
- High-speed operation with typically 80 ns response time
- Wide operating voltage range from single 5V to ±15V supplies
- Uncommitted collector outputs compatible with RTL, DTL, and TTL logic families
- Capable of driving lamps and relays at currents up to 25 mA
Applications
- Relay driver circuits
- Window detector applications
- Digital logic interface systems
Procurement Notes
Verify that the procurement specification explicitly requires the 'MDE' suffix designation for the die sale format. Confirm that the receiving facility has the necessary infrastructure for handling bare dies, including appropriate ESD protection measures during storage and assembly. Ensure that quality conformance inspection requirements align with the manufacturer's production data standards.
Selection Notes
Select this component when high-speed comparison is required alongside the ability to drive moderate load currents directly. It serves as a versatile alternative to older devices like the LM711, offering faster response times and lower package counts. Consider the higher power dissipation relative to slower comparators when designing thermal management strategies for the application.
Part Context
This part belongs to the LM119 family of precision high-speed dual comparators. It is fabricated on a single monolithic chip and offers higher gain and lower input currents compared to similar legacy devices. The family is designed primarily for digital logic supply applications but is fully specified for wider voltage ranges, providing versatility in various electronic designs.
Replacement Considerations
Public confirmed substitute part numbers include LM119QML and LM119QML-SP.
