LM119J/883/MABI

Overview

The LM119J/883/MABI 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 compatible with RTL, DTL, and TTL, capable of driving loads up to 25 mA. The device offers a typical response time of 80 ns at ±15V, a maximum input current of 1 µA across temperature, and a minimum fan-out of 2 per side. It operates from -55°C to 125°C.

Feature Summary

Radiation-tolerant design ensuring high dose rate performance of 100 krad(Si) without enhanced low-dose-rate sensitivity (ELDRS).
High common-mode slew rate and fast response times suitable for precision timing applications.
Uncommitted collector output stage allows flexible interfacing with various logic families and direct drive of lamps or relays.

Applications

Window detectors requiring precise voltage threshold monitoring.
Relay driver circuits utilizing the high-current output capability.
Digital logic power supply monitoring systems.

Procurement Notes

Verify that the specific MABI suffix corresponds to the intended radiation qualification level and package variant within the LM119QML family. Confirm compliance with MIL-STD-883 testing requirements for Group 5 subgroups if space or military certification is required. Ensure the ordering part number matches the desired ceramic packaging option such as CDIP or TO-100.

Selection Notes

Select this component when radiation hardness is critical for aerospace or defense environments. It provides superior speed compared to older comparators like the LM711 while maintaining lower input currents than devices like the LM710. Consider the thermal resistance characteristics of the ceramic package for heat dissipation in enclosed assemblies.

Part Context

This part belongs to the LM119QML family, which includes variants qualified for military and space applications. It shares architectural similarities with the commercial LM119 but undergoes rigorous screening and testing protocols defined by MIL-STD-883. The family encompasses multiple package options including CDIP, LCCC, and TO-100 to suit different mounting and environmental needs.
