100398PC

Overview

The Fairchild Semiconductor 100398PC is a mixed-signal translator housed in a 24-pin PDIP package. It functions as a bidirectional level shifter with one circuit and four channels per circuit. The device translates between ECL input signals and TTL output signals, facilitating interface compatibility between different logic families.

Feature Summary

• Bidirectional signal translation capability
• Interface bridging between ECL and TTL logic levels
• Quad channel configuration within a single circuit

Applications

• ECL to TTL level shifting interfaces
• TTL to ECL level shifting interfaces
• Mixed-signal system interconnects requiring voltage domain translation

Procurement Notes

Verify the specific datasheet version for absolute maximum ratings and recommended operating conditions. Confirm that the 24-PDIP package meets mechanical requirements. Ensure supply chain sources provide original Fairchild Semiconductor components to guarantee performance specifications are met.

Selection Notes

Select this component when bidirectional translation between ECL and TTL domains is required. The quad-channel design reduces board space compared to discrete solutions. Verify signal integrity requirements match the device capabilities for the specific application environment.

Part Context

This part belongs to the Fairchild Semiconductor logic family of translators. It addresses the need for reliable communication between high-speed ECL circuits and standard TTL systems. The DIP-24 package allows for through-hole mounting in legacy or specific industrial designs.

Replacement Considerations

Check for equivalent parts from other manufacturers offering similar ECL-to-TTL bidirectional translation in a 24-pin DIP package. Verify pinout compatibility before substitution.
