100324PC

Overview

The Fairchild Semiconductor 100324PC is a low-power hex TTL-to-ECL translator housed in a 24-pin plastic DIP package. It functions as a unidirectional voltage level converter, translating six channels from Transistor-Transistor Logic (TTL) standards to Emitter-Coupled Logic (ECL) levels. The device operates within a specified temperature range and is designed for applications requiring interface between these two distinct logic families.

Feature Summary

• Unidirectional translation from TTL input to ECL output
• Hex configuration providing six independent conversion channels
• Low power consumption design suitable for energy-efficient systems

Applications

• Interfacing TTL-based microprocessors with ECL memory systems
• Converting control signals between mixed logic family circuits
• Data bus translation in legacy computing architectures

Procurement Notes

Verify the specific manufacturer source, as Fairchild Semiconductor assets are now managed by onsemi. Confirm RoHS compliance status, as listings indicate variations such as ROHS3 compliant or non-compliant versions depending on production batch and era. Ensure the package type matches the required PCB footprint for the 24-pin DIP form factor.

Selection Notes

Select this component when a unidirectional path from TTL to ECL is required. Verify that the system does not need bidirectional translation, which would require a different part number. Check operating temperature specifications against environmental conditions. Consider pin compatibility if replacing older designs.

Part Context

This component belongs to the 100K series of logic devices produced by Fairchild Semiconductor. It serves as a specialized interface chip bridging the gap between standard TTL logic levels and the faster, lower-voltage ECL standards. Similar parts in the lineup include the 100329PC for bidirectional translation.
