Overview
The LM193 MDE is a die-sale dual precision voltage comparator from Texas Instruments, designed for single or split power supply operation. It features an input common-mode voltage range that includes ground and differential input voltage capability equal to the supply voltage. The device offers low supply current drain independent of voltage magnitude and outputs compatible with TTL, DTL, ECL, MOS, and CMOS logic systems.
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 two comparators
- Input common-mode voltage range includes ground even when operated from a single supply
- Differential input voltage range equals the full supply voltage
Applications
- Limit comparators
- Simple analog to digital converters
- Pulse, squarewave and time delay generators
- Wide range VCOs
- MOS clock timers
Procurement Notes
Verify the specific radiation qualification status and lot traceability requirements against MIL-STD-883 Method 5005 Group A standards before procurement. Confirm that the die-sale format meets your packaging and assembly capabilities. Ensure all unused comparator inputs are tied to the negative supply to prevent oscillation during operation.
Selection Notes
Select this component for applications requiring high precision and radiation hardness in space or military environments. The wide supply voltage range allows flexibility in system design. Consider the low power drain suitable for battery operation. Verify thermal management needs based on the package type and ambient temperature conditions.
Part Context
This part belongs to the LM193 series of low-power, low-offset voltage dual comparators. It shares functional similarities with the LM293, LM393, and LM393W but is distinguished by its radiation-hardened specifications and availability as a bare die for custom packaging solutions.

FAQ
Can the differential input voltage exceed the positive supply voltage?
Yes, positive excursions of the input voltage may exceed the power supply level without damaging the device, provided the other input remains within the common-mode range.
Is bypassing required across the power supply line?
It is usually unnecessary to use a bypass capacitor across the power supply line for this device.
