Overview
The HFA7-0003-9 is a general-purpose comparator manufactured by Harris Corporation, designed for ECL logic compatibility. It operates within an extended temperature range of -40°C to +85°C and features a maximum propagation delay of 2.4ns. The device is housed in an 8-CDIP (CERDIP) package with a width of 0.300 inches (7.62mm). It does not include internal hysteresis. The component is classified as non-RoHS compliant and has a Moisture Sensitivity Level (MSL) of 3, corresponding to a 168-hour limit.
Feature Summary
- ECL logic interface compatibility for high-speed digital applications
- General-purpose comparator functionality without internal hysteresis
- Extended industrial operating temperature range from -40°C to +85°C
Applications
- High-speed digital signal processing circuits
- ECL-based logic interfacing systems
- Industrial control environments requiring wide temperature tolerance
Procurement Notes
Verify RoHS compliance status prior to integration, as this specific part number is documented as non-compliant. Confirm MSL level 3 handling requirements during storage and assembly processes. Ensure the 8-CDIP package dimensions align with the target PCB footprint. Validate that the absence of internal hysteresis meets the noise immunity requirements of the specific application circuit design.
Selection Notes
Select this component when ECL compatibility is required for the system architecture. The 2.4ns propagation delay supports high-frequency switching needs. Consider the ceramic DIP package for robustness in harsh environments. Verify that the lack of built-in hysteresis allows for external resistor implementation if noise filtering is necessary for the specific signal integrity profile.
Part Context
This comparator belongs to the Harris Corporation linear integrated circuit portfolio, specifically tailored for high-speed digital applications. The HFA7 series utilizes ECL technology to achieve fast response times. The HFA7-0003-9 variant is distinct from operational amplifiers in the same family, such as the HFA7-0005-5, by its dedicated comparator function and specific pinout configuration for differential input stages.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching ECL voltage levels, 8-pin CERDIP packaging, and comparable propagation delay specifications. Verify functional equivalence through detailed datasheet comparison before substitution.
