100325QC

Overview

The Fairchild Semiconductor 100325QC is a low-power hex ECL-to-TTL translator designed to interface F100K logic levels with TTL standards. It contains six independent unidirectional translation circuits within a single package. The device utilizes differential inputs for each channel, ensuring reliable signal conversion in mixed-signal environments. Packaged in a 28-pin PLCC (11.5x11.5 mm) housing, it serves as a dedicated level shifter for digital systems requiring ECL to TTL compatibility.

Feature Summary

• Provides six independent channels for converting ECL signals to TTL logic levels
• Features differential input architecture for each translation circuit
• Designed specifically for low-power operation in mixed-signal applications

Applications

• Interfacing F100K logic families with TTL-based systems
• Digital signal translation in mixed-voltage electronic circuits
• Level shifting between ECL sources and TTL destinations

Procurement Notes

Verify the manufacturer marking matches Fairchild Semiconductor specifications. Confirm the package type is 28-PLCC with the correct body dimensions. Ensure the suffix QC denotes the specific temperature range and packaging variant required for your design. Cross-reference the datasheet revision date to confirm technical parameters match your system requirements before procurement.

Selection Notes

Select this component when interfacing F100K logic with TTL loads is required. It is suitable for designs needing multiple parallel translation channels in a compact footprint. Consider the low-power characteristic if thermal management is a constraint. Verify that the unidirectional nature of the circuits aligns with your signal flow direction requirements.

Part Context

This part belongs to the family of logic translators produced by Fairchild Semiconductor. It addresses the need for bridging different logic voltage standards in digital electronics.
