100164FC

Overview

The 100164FC is a high-speed ECL buffer and line driver manufactured by National Semiconductor, now part of Texas Instruments. It operates within the MC100L logic family, designed for demanding digital applications requiring fast signal propagation. The device is housed in a 24-pin ceramic flatpack (QFF) package with tin/lead terminal plating. It supports a wide operating temperature range suitable for industrial environments. Key electrical characteristics include a maximum power supply current of 65 mA and operation at standard ECL voltage levels.

Feature Summary

• High-speed differential signaling capability inherent to ECL technology
• Robust ceramic packaging for enhanced thermal and mechanical stability
• Designed for reliable performance in harsh industrial temperature ranges

Applications

• High-speed data transmission lines
• Industrial control systems requiring noise immunity
• Test and measurement equipment interfaces

Procurement Notes

Verify component authenticity through authorized distributors or certified secondary market suppliers due to potential obsolescence. Confirm lot codes and date codes against current inventory records. Ensure proper handling procedures for ceramic packages are followed during installation. Check for RoHS compliance status as original specifications may predate modern environmental regulations. Validate pinout compatibility with existing PCB footprints before integration.

Selection Notes

Select this component when ECL speed advantages are critical over CMOS or TTL alternatives. Consider the specific thermal requirements of the ceramic flatpack enclosure. Evaluate system power budgets against the 65 mA maximum current draw. Ensure interface circuits match ECL voltage swing standards. Verify that the operating environment stays within the specified temperature limits for optimal reliability.

Part Context

This part belongs to the MC100L series of emitter-coupled logic devices produced by National Semiconductor. The series was widely used in telecommunications and computing infrastructure before transitioning to newer technologies under Texas Instruments ownership. The 100164FC specifically serves as a buffer/driver within this lineage, offering high-frequency performance capabilities typical of the era's high-speed digital design needs.

Replacement Considerations

Consult official Texas Instruments documentation for direct cross-references within the MC100L family. Verify functional equivalence with other ECL buffers if exact replacement is unavailable. Check pin-to-pin compatibility for any alternative packages offered by manufacturers.
