100124FC

Overview

The 100124FC is a mixed-signal translator manufactured by National Semiconductor, designed for unidirectional signal conversion between TTL and ECL logic families. It integrates six independent channels within a single circuit configuration, facilitating interface compatibility in systems requiring level shifting. The device operates within a temperature range of 0°C to 85°C and utilizes an inverted output type to ensure proper signal alignment. Packaged in a 24-lead CFP (Ceramic Flatpack), this component serves as a dedicated solution for translating input signals from TTL standards to ECL100K output requirements.

Feature Summary

• Unidirectional translation capability between TTL input and ECL output logic levels
• Six-channel integration within a single circuit package for efficient board space utilization
• Inverted output configuration ensuring correct signal polarity for ECL interfacing

Applications

• Interface bridging between TTL-based control units and ECL processing modules
• Signal level conversion in high-speed digital communication systems
• System integration where mixed logic family compatibility is required

Procurement Notes

Verify the manufacturer designation as National Semiconductor, noting that corporate assets may have transferred to Texas Instruments. Confirm the specific package variant matches the 24-CFP specification. Ensure the operating temperature range aligns with your system's environmental constraints. Cross-reference the part number against official distributor catalogs to confirm availability and authenticity before procurement.

Selection Notes

Select this component when unidirectional conversion from TTL inputs to ECL outputs is required. The six-channel density makes it suitable for parallel data buses or multi-line control interfaces. Consider the ceramic flatpack package for applications demanding robust thermal performance and reliable surface mounting. Verify that the inverted output characteristic meets the downstream ECL receiver requirements without additional inversion stages.

Part Context

This component belongs to the National Semiconductor logic translator category, specifically addressing the interface gap between different logic families. It is distinct from general-purpose buffers or inverters by its specialized function of converting voltage levels and signal characteristics between TTL and ECL standards. The device supports legacy system upgrades and hybrid architectures where multiple logic types must coexist.
