Overview
The LM119W/883 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 uncommitted collector outputs capable of driving loads up to 25 mA and offers a typical response time of 80 ns at ±15 V. The device ensures radiation tolerance with a high dose rate capability of 100 krad(Si) and is ELDRS free. It operates within an ambient temperature range of -55°C to 125°C.
Feature Summary
- High-speed dual comparator design with uncommitted collector outputs
- Radiation hardened with 100 krad(Si) high dose rate tolerance
- ELDRS free construction for reliable space applications
- Wide operating voltage range from single 5V to ±15V supplies
Applications
- Relay driver circuits
- Window detector configurations
- Military and defense electronic systems
- Space-based application hardware
Procurement Notes
Verify the specific suffix indicates the CFP (NAD) ceramic package configuration. Confirm compliance with MIL-STD-883 standards for Group 5 quality conformance inspection. Ensure the procurement order specifies the correct radiation qualification level required for the target environment.
Selection Notes
Select this component when radiation hardness is mandatory for dual comparator applications. It provides higher gain and lower input current compared to standard commercial devices like the LM710. Consider the thermal resistance characteristics of the ceramic package for heat dissipation requirements in enclosed military enclosures.
Part Context
This part belongs to the LM119QML family, which includes variants such as LM119J/883 and LM119H/883. These devices are qualified versions of the standard LM119 comparator, specifically engineered for harsh environments. The W/883 designation identifies the specific ceramic flat pack variant within this radiation-tolerant product line.
