FIN1017K8K

Overview

The FIN1017K8K is a high-speed ECL (Emitter-Coupled Logic) differential line receiver manufactured by Fairchild Semiconductor. It operates within the ECL10K family, designed for reliable signal reception in high-frequency digital systems. The device features a single differential receiver configuration with an output driver stage. It utilizes a ceramic flatpack package with 16 terminals, suitable for surface-mount or through-hole integration depending on specific board design requirements. The component is rated for operation up to a maximum temperature of 70 °C and requires a -5.2 V power supply typical for ECL logic families.

Feature Summary

• High-speed differential signal reception capability optimized for ECL10K logic standards
• Integrated output driver stage for signal buffering and transmission
• Robust ESD protection mechanisms inherent to the ECL10K architecture
• Ceramic packaging providing thermal stability and mechanical durability

Applications

• High-speed data communication interfaces requiring differential signaling
• Computer memory bus architectures utilizing ECL logic levels
• Telecommunications equipment signal processing stages
• Test and measurement instruments requiring precise timing recovery

Procurement Notes

Verify the specific suffix K8K against the manufacturer's current datasheet to confirm pinout compatibility and package variant. Ensure the procurement source provides original Fairchild Semiconductor documentation rather than third-party interpretations. Check for RoHS compliance status as older ECL components may not meet modern environmental regulations. Confirm availability of equivalent leaded or lead-free versions if required by assembly processes.

Selection Notes

Select this component when designing systems that strictly adhere to ECL10K voltage levels and timing characteristics. Consider the ceramic flatpack form factor for applications requiring high thermal dissipation or radiation hardness compared to plastic packages. Evaluate the need for differential receivers versus single-ended alternatives based on noise immunity requirements in the target environment. Verify power supply stability at -5.2 V to ensure proper logic threshold operation.

Part Context

The FIN1017K8K belongs to the Fairchild ECL10K series, a legacy high-performance logic family known for speed and low noise. This series was widely used in mainframe computers and high-end networking gear before the industry shifted toward lower voltage CMOS technologies. The 'FIN' prefix typically denotes ECL devices from Fairchild, while '1017' identifies the specific receiver function within the product line.

Replacement Considerations

Direct replacements include other ECL10K differential receivers such as the MC10171 or similar variants from Motorola/NXP. Cross-reference pinouts carefully as ECL packages vary significantly between manufacturers. Consider upgrading to newer low-voltage ECL or CML technologies if system redesign is permissible, as legacy ECL parts may have limited long-term supply assurance.
