100329DC

Overview

The Fairchild Semiconductor 100329DC is an octal registered bidirectional mixed-signal translator IC. It facilitates signal conversion between TTL and 100K ECL logic families in both directions. The device features eight channels per circuit, supporting high-density data translation tasks. It is housed in a 24-pin CERDIP package designed for through-hole mounting. The component operates within a temperature range of 0°C to 85°C (TC). This integrated circuit is engineered for reliable interface applications requiring robust level shifting between distinct logic standards.

Feature Summary

• Bidirectional translation capability between TTL and 100K ECL logic levels
• Octal configuration providing eight independent channels per circuit
• Registered design ensuring stable state retention during transitions

Applications

• Interface circuits connecting TTL-based microprocessors to ECL memory systems
• Data bus bridging in legacy computing architectures
• Signal conditioning in industrial control systems utilizing mixed logic standards

Procurement Notes

Verify the specific manufacturer source, as Fairchild Semiconductor assets are now managed by ON Semiconductor. Confirm the package type matches the required 24-CERDIP specification for your PCB layout. Ensure the operating temperature range meets your environmental requirements. Check for active status availability from authorized distributors. Validate that the input/output signals align with your system's TTL and ECL voltage levels.

Selection Notes

Select this component when interfacing systems requiring bidirectional data flow between TTL and 100K ECL domains. The octal channel count suits applications needing multiple parallel signal conversions. Consider the registered nature of the device for timing stability in synchronous systems. Evaluate the through-hole packaging constraints against your board design capabilities. Ensure compatibility with existing logic family voltages before integration.

Part Context

This part belongs to the category of mixed-signal translators and level shifters. It serves as a bridge between different logic families, specifically addressing the voltage and speed differences between TTL and ECL technologies. Such components are critical in systems where legacy equipment must communicate with modern or specialized high-speed logic interfaces.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout and electrical specifications carefully if considering alternative manufacturers. Ensure any replacement maintains the bidirectional functionality and octal channel configuration.
