100324QC

Overview

The Fairchild Semiconductor 100324QC is a mixed-signal translator IC designed for unidirectional logic level conversion. It functions as a hex translator, converting TTL logic levels to 100K ECL logic levels. The device features six independent channels within a single circuit configuration. Inputs are compatible with standard or Schottky TTL signals. The component is housed in a 28-pin PLCC package with dimensions of 11.51x11.51 mm.

Feature Summary

• Unidirectional translation from TTL to 100K ECL logic levels
• Hex configuration providing six independent conversion channels
• Input compatibility with standard and Schottky TTL families

Applications

• Interfacing TTL-based microprocessors with ECL memory systems
• Logic level shifting in mixed-technology digital circuits
• Signal translation between TTL input sources and ECL output loads

Procurement Notes

Verify the specific manufacturer designation, as Fairchild Semiconductor assets were acquired by ON Semiconductor. Confirm the package type is 28-PLCC and check RoHS compliance status against current production records. Ensure the part number suffix matches the required temperature range and packaging format for your specific supply chain requirements.

Selection Notes

Select this component when unidirectional conversion from TTL inputs to 100K ECL outputs is required. It is suitable for applications needing six isolated translation channels. Consider the 28-PLCC package constraints for PCB layout. Verify that the target system operates within the specified voltage ranges for both TTL inputs and ECL outputs before implementation.

Part Context

This component belongs to the family of low-power hex TTL-to-ECL translators produced by Fairchild Semiconductor. These devices facilitate integration between different logic families without requiring external discrete components. The 100324QC specifically addresses the need for reliable signal translation in legacy or hybrid digital systems utilizing these distinct logic standards.

Replacement Considerations

Check for equivalents from ON Semiconductor following the acquisition of Fairchild's logic product line. Verify pinout compatibility and electrical specifications such as propagation delay and voltage thresholds. Ensure any substitute maintains the same 28-PLCC package form factor and unidirectional functionality.
