100329ADC

Overview

The Fairchild Semiconductor 100329ADC is an octal registered bidirectional translator designed to convert logic levels between TTL and 100K ECL families in both directions. It integrates eight translation channels with register functionality within a single integrated circuit. The device operates using built-in voltage-level shifting mechanisms to ensure signal integrity across different logic standards. It is housed in a 24-pin CERDIP package, providing a robust solution for mixed-signal interface applications requiring reliable level translation.

Feature Summary

• Bidirectional translation capability between TTL and 100K ECL logic families
• Octal configuration with integrated registration for data storage
• Built-in voltage-level shifting for direct interface compatibility

Applications

• Interfacing TTL-based systems with ECL-based memory or processors
• Mixed-logic system architecture design
• Signal translation in high-speed digital communication interfaces

Procurement Notes

Verify the specific package variant, as the part number indicates a 24-pin CERDIP configuration. Confirm that the application requires 100K ECL speed class rather than faster ECL variants. Ensure supply chain sources provide original manufacturer documentation to validate authenticity and revision history before integration into critical designs.

Selection Notes

Select this component when bidirectional conversion between standard TTL and 100K ECL is required without external level-shifting circuits. The integrated register feature simplifies timing control in synchronous systems. Consider the 24-pin CERDIP package constraints for board layout and thermal management compared to surface-mount alternatives.

Part Context

This component belongs to the 100329 series of mixed-signal translators from Fairchild Semiconductor. These devices are engineered to bridge the gap between different logic families, specifically addressing the voltage and current drive differences between TTL and ECL technologies. The series supports various packaging options to accommodate different assembly requirements.

Replacement Considerations

Check for equivalent octal bidirectional translators with similar ECL/TTL compatibility. Verify pinout compatibility if substituting with other manufacturers' parts. Ensure the replacement supports the same 100K ECL speed specification and includes integrated registration features.
