Overview
The LM193AJ/883 is a dual precision voltage comparator manufactured by Texas Instruments, designed for operation from single or split power supplies ranging from 2.0 VDC to 36 VDC. It features an input common-mode voltage range that includes ground and offers low supply current drain independent of the supply voltage magnitude. The device provides open-collector outputs compatible with TTL, DTL, ECL, MOS, and CMOS logic systems. It operates within a temperature range of -55°C to +125°C.
Feature Summary
- Radiation guarantee with Total Ionizing Dose tolerance of 100 krad(Si) and ELDRS-free performance
- Low offset voltage specification as low as 2.0 mV maximum for high precision applications
- Input common-mode voltage range includes ground even when operated from a single power supply
- Open-collector output allows direct interfacing with various logic families including MOS
Applications
- Limit comparators in signal processing circuits
- Simple analog to digital converters
- Pulse, squarewave and time delay generators
- Wide range voltage controlled oscillators (VCO)
- MOS clock timers and multivibrators
Procurement Notes
Verify the specific ordering suffix matches the required radiation qualification and package type. Confirm compliance with MIL-STD-883 Method 5005 Group A inspection requirements. Ensure the procurement channel supports military-grade components and provides necessary traceability documentation for space or defense applications.
Selection Notes
Select this component for applications requiring radiation hardness and high precision voltage comparison. The wide supply voltage range and ground-referenced inputs simplify circuit design in single-supply systems. Verify that the open-collector output configuration aligns with the system's pull-up resistor requirements and logic interface needs.
Part Context
This part belongs to the LM193 series of low power, low offset voltage dual comparators. It is specifically qualified under the QML (Military) standard, ensuring reliability for harsh environments. The /883 suffix indicates compliance with MIL-STD-883 testing standards, distinguishing it from commercial variants.

FAQ
Does the LM193AJ/883 exhibit enhanced low dose rate sensitivity?
No, low dose rate testing has been performed on a wafer-by-wafer basis with no enhanced low dose rate sensitivity effect.
Can the differential input voltage exceed the positive supply voltage?
Yes, positive excursions of input voltage may exceed the power supply level without damaging the device, provided the other voltage remains within the common-mode range.
