67413AJ

Overview

The Advanced Micro Devices 67413AJ is an asynchronous First-In-First-Out (FIFO) memory device designed for high-speed data buffering applications. It features a 64 x 5 bit memory organization, providing uni-directional data flow capabilities. The component operates with a maximum data rate of 35MHz and requires a supply voltage range of 4.75 V to 5.25 V. Packaged in a 20-pin Ceramic Dual In-Line Package (CDIP), this logic interface buffer facilitates efficient data transfer between systems operating at different clock speeds.

Feature Summary

• Asynchronous FIFO architecture enables efficient data transfer between independent clock domains
• Uni-directional data flow design simplifies integration into serial communication interfaces
• High-speed operation supports data rates up to 35MHz for rapid processing

Applications

• Serial-to-parallel data conversion buffers
• Interface buffering between microprocessors and peripheral devices
• Data acquisition system input staging

Procurement Notes

Verify the specific suffix 'AJ' corresponds to the ceramic dual in-line package variant when sourcing replacements. Confirm that the required supply voltage aligns with standard 5V logic levels. Ensure compatibility with existing board layouts due to the 20-pin CDIP footprint dimensions. Check for end-of-life status as this model may be discontinued by the manufacturer.

Selection Notes

Select this component when a simple, unidirectional buffering solution is required for moderate-speed asynchronous data transfers. The 64-word depth provides adequate staging for burst data without excessive latency. Consider the physical package constraints and verify that the 5V logic family matches the surrounding circuitry requirements for reliable signal integrity.

Part Context

This part belongs to the AMD 674xx series of asynchronous FIFO memories, which were widely used in legacy computing and industrial control systems. These devices served as critical interface components before the prevalence of complex programmable logic devices. The 67413AJ specifically addresses the need for reliable data synchronization in systems requiring distinct read and write clock domains.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility if considering generic asynchronous FIFO alternatives from other manufacturers.
