Overview
The LM193AH/883 is a dual precision voltage comparator manufactured by Texas Instruments, designed for high-reliability applications. It operates from a single or split power supply ranging from 2.0 VDC to 36 VDC (±1.0 V to ±18 V). The device features a low input offset voltage of 2.0 mV maximum and very low supply current drain of 0.4 mA. It includes radiation guarantees with a Total Ionizing Dose tolerance of 100 krad(Si) and is ELDRS free. The input common-mode voltage range includes ground, and the output is compatible with TTL, DTL, ECL, MOS, and CMOS logic systems.
Feature Summary
- Radiation tolerant design with guaranteed performance up to 100 krad(Si) total ionizing dose
- ELDRS free construction suitable for space-based environments
- High precision with low input offset voltage specification
- Input common-mode voltage range includes ground potential
Applications
- Military and defense electronic systems
- Space-based satellite applications
- Limit comparators in harsh environments
- Analog-to-digital converters requiring radiation hardness
Procurement Notes
Verify that the component is sourced through authorized channels to ensure authenticity. Confirm the presence of QML certification markings on the package. Check the datasheet revision history for any updates to electrical characteristics. Ensure the ordering suffix matches the required radiation qualification level. Validate the lot trace code against military standards documentation.
Selection Notes
Select this component when radiation hardness is mandatory for the application environment. Consider the TO-99 ceramic package for superior thermal and mechanical stability compared to plastic packages. Evaluate the low supply current requirement against battery-operated system constraints. Verify that the input signal levels remain within the specified common-mode range including ground.
Part Context
This part belongs to the LM193 series of low-power, low-offset voltage dual comparators. It is specifically qualified under the QML standard for military and aerospace use. The /883 suffix indicates compliance with MIL-STD-883 testing requirements. It serves as a robust alternative to commercial grade comparators in extreme operating conditions.

FAQ
Is the LM193AH/883 sensitive to enhanced low dose rate effects?
No, the device is explicitly specified as ELDRS free.
Can the input voltage exceed the positive supply rail?
Yes, positive excursions of input voltage may exceed the power supply level without damage, provided the other input remains within the common-mode range.
