100329APC

Overview

The Fairchild Semiconductor 100329APC is an octal bidirectional voltage level translator with register, designed for ECL to TTL or TTL to ECL conversion. It operates within a supply voltage range of 4.5 V to 5.5 V and features a propagation delay of 7.2 ns. The device supports through-hole mounting in a DIP-24 package and functions across an operating temperature range of 0°C to +85°C.

Feature Summary

• Octal bidirectional translation between ECL and TTL logic levels
• Integrated register functionality for data storage during transfer
• Through-hole DIP-24 packaging for standard circuit board integration

Applications

• Interfacing ECL-based systems with TTL-compatible components
• Voltage level shifting in mixed-logic digital circuits
• Data bus translation in legacy computer architectures

Procurement Notes

Verify the specific suffix 'APC' against official onsemi documentation, as public records primarily list the 'PC' variant. Confirm current lifecycle status, as related models are marked obsolete. Ensure compatibility with existing DIP-24 footprints and validate that the 4.5V to 5.5V supply range meets system requirements before procurement.

Selection Notes

Select this component when bidirectional ECL-TTL translation with internal latching is required. Verify that the 7.2 ns propagation delay aligns with system timing constraints. Ensure the DIP-24 form factor fits the mechanical design. Check for RoHS compliance details if environmental regulations apply to the target assembly.

Part Context

This part belongs to the 1003 series of logic ICs manufactured by onsemi (formerly Fairchild Semiconductor). It falls under the category of voltage level translators. The manufacturer integrates Fairchild products into its portfolio, maintaining continuity for legacy logic families used in industrial and computing applications.

Replacement Considerations

Public records indicate the 100329PC variant is obsolete. Verify if the 100329APC is also discontinued. Consult onsemi for active equivalents or cross-reference with other octal ECL/TTL translators from compatible manufacturers if availability is restricted.
