The device operates with open-collector outputs and supports a supply voltage of 5 V. It is designed for bipolar applications with an operating temperature range from -55 °C to +125 °C.
Comparators Feature Summary
- Quad comparator configuration providing four independent comparison functions within a single package.
- Bipolar technology construction ensuring stable performance across wide temperature extremes.
- Open-collector output stage allowing flexible interfacing with various logic families.
Comparators Applications
- High-speed signal processing circuits requiring precise threshold detection.
- Industrial control systems operating in extreme environmental conditions.
- Analog-to-digital conversion interfaces utilizing fast response times.
Comparators Procurement Notes
Verify the specific suffix 'F' against manufacturer documentation to confirm package and material specifications. Ensure compatibility with existing board layouts for CDIP14 footprints. Confirm RoHS status as the component may not be compliant. Validate supply chain sources for vintage or discontinued semiconductor parts.
Comparators Selection Notes
Select this component when a quad comparator with low offset voltage and high speed is required. Consider the ceramic DIP-14 package for thermal stability and durability. Evaluate the 5 V supply requirement against system power constraints. Compare response time specifications with other available comparators for timing-critical designs.
Comparators Part Context
The CA0139AF belongs to the Harris Corporation analog mixed-signal IC family, specifically within the amplifier and comparator circuit category. Harris was known for high-performance linear and mixed-signal semiconductors before its acquisition. This part represents legacy technology still referenced in industrial and military applications requiring robust analog components.
Comparators Replacement Considerations
Consult official datasheets for pin-compatible alternatives from current manufacturers. Verify electrical parameters such as offset voltage and response time match original requirements. Check package dimensions for mechanical fit in existing assemblies.
