Overview
The Texas Instruments 7700801DA is a quad differential comparator belonging to the LM139-MIL series. It features four independent voltage comparators designed for military-grade applications. The device operates within a supply voltage range of ±15V to 30V and is housed in a 14-pin CFPAK tube package.
Feature Summary
- Quad differential comparator architecture
- Military-grade component qualification
Applications
- Microcomputer reset controllers
- Microprocessor system supervision
- Voltage monitoring circuits
Procurement Notes
Verify RoHS compliance status as sources indicate 'No'. Confirm the specific military grade designation matches project requirements. Ensure the 14-pin CFPAK tube packaging aligns with assembly capabilities. Cross-reference the manufacturer part number against official Texas Instruments documentation to validate authenticity.
Selection Notes
Select this component for high-reliability environments requiring quad comparison functions. The wide supply voltage range supports diverse power systems. Verify thermal management needs for the CFPAK package. Ensure input common-mode ranges meet circuit specifications.
Part Context
This part is part of the LM139 family, specifically the military variant. It serves as a standalone voltage detector or analog-to-digital converter precursor. The quad configuration allows multiple threshold comparisons in a single package.
Replacement Considerations
Check for LM139 equivalents. Verify pin compatibility and electrical parameters. Ensure military grade requirements are met by substitutes.
