100398QCX

Overview

The Fairchild Semiconductor 100398QCX is a mixed-signal translator integrated circuit designed for bidirectional voltage level shifting. It features a single circuit with four independent channels, enabling data translation between different logic families or voltage domains. The device is housed in a 28-PLCC package, specifically a 28-LCC (J-Lead) configuration with dimensions of 11.51x11.51 mm. This component facilitates interface connections where signal levels must be adapted to ensure compatibility between systems operating at distinct voltage thresholds.

Feature Summary

• Bidirectional data translation capability for mixed-signal applications
• Four independent channels within a single circuit configuration
• Surface mount packaging in a 28-pin PLCC format

Applications

• Voltage level shifting between disparate logic families
• Interface bridging in mixed-voltage digital systems
• Signal translation for peripheral connectivity

Procurement Notes

Verify the manufacturer part number 100398QCX against official Fairchild Semiconductor documentation to confirm specifications. Ensure the package type matches the required 28-PLCC form factor. Check RoHS compliance status if environmental regulations apply. Confirm that the bidirectional translator functionality aligns with the specific voltage requirements of the target application before procurement.

Selection Notes

Select this component when bidirectional level shifting is required for four channels simultaneously. The 28-PLCC package suits surface mount assembly processes. Consider the voltage range compatibility between source and destination logic levels. Verify that the single-circuit architecture meets the system's timing and throughput requirements without necessitating multiple discrete translators.

Part Context

This part belongs to the Fairchild Semiconductor family of mixed-signal translators. It serves as a solution for interfacing components with differing voltage standards. The 100398 series typically addresses challenges in system integration where direct connection is not feasible due to voltage mismatches. It complements other interface solutions by providing a compact, multi-channel approach to signal adaptation.

Replacement Considerations

Consult official substitution guides for equivalent bidirectional translators. Verify pinout compatibility and channel count before replacing. Ensure voltage ratings match the original design constraints.
