Overview
The LM193H/883 is a dual precision voltage comparator manufactured by Texas Instruments, designed for high-reliability applications. It operates from a single supply ranging from 2.0 VDC to 36 VDC or split supplies of ±1.0 V to ±18 V. The device features very low power supply current drain of 0.4 mA, independent of the supply voltage magnitude. Input common-mode voltage includes ground, and differential input voltage equals the supply voltage. It offers low input biasing current (25 nA typ) and low output saturation voltage (250 mV at 4 mA). The outputs are compatible with TTL, DTL, ECL, MOS, and CMOS logic systems.
Feature Summary
- Radiation guarantee with Total Ionizing Dose up to 100 krad(Si) and ELDRS free capability
- Low power supply current drain independent of supply voltage
- Input common-mode voltage range includes ground
- Output voltage compatible with various logic systems
Applications
- Limit comparators
- Simple analog to digital converters
- Pulse, squarewave and time delay generators
- Wide range VCO
- MOS clock timers
Procurement Notes
Verify that the ordering suffix /883 corresponds to the specific package type and radiation qualification required for your application. Confirm the exact part marking matches the datasheet specifications. Ensure compliance with MIL-STD-883 quality conformance inspection standards if specified in your design requirements. Check for any additional environmental or reliability certifications needed for military or space-grade deployments.
Selection Notes
Select this component when radiation tolerance and low power consumption are critical. It is suitable for battery-operated systems due to its low supply current. Consider it for applications requiring direct interface with TTL and CMOS logic without level shifting. Verify that the operating temperature range of -55°C to +125°C meets your environmental constraints.
Part Context
The LM193 series consists of two independent precision voltage comparators. The LM193H/883 variant is specifically qualified for harsh environments, offering radiation hardness. It is part of a broader family including LM193A and LM193QML, sharing similar electrical characteristics but differing in packaging and qualification levels. The device is designed to operate efficiently over a wide voltage range.
