C67401N

FIFOs Memory Overview

The C67401N is an asynchronous FIFO memory device manufactured by Advanced Micro Devices. It features a 64 x 4 bit organization, providing 64 words of 4-bit width. The component operates at a maximum frequency of 10MHz with a typical access time of 45ns. It is housed in a 16-pin PDIP package and functions as a unidirectional buffer for data storage applications.

FIFOs Memory Feature Summary

• Asynchronous operation allows independent read and write clock domains
• Unidirectional data flow for simple buffering tasks
• High-speed fall-through architecture minimizes latency

FIFOs Memory Applications

• Data buffering between asynchronous systems
• Interface bridging for digital signal processing
• Temporary data storage in communication protocols

FIFOs Memory Procurement Notes

Verify the specific suffix (e.g., N) against the manufacturer's official datasheet to confirm pinout and electrical characteristics. Ensure the package type matches the design requirements. Check for obsolescence status as this is an older component from Advanced Micro Devices. Confirm availability through authorized distributors or verified surplus suppliers.

FIFOs Memory Selection Notes

Select this part when a small, fast, unidirectional buffer is required. The 64x4 depth suits narrow data paths. Compare access times and power consumption with newer alternatives if available. Ensure voltage levels match the system logic family. Consider physical size constraints due to the PDIP package.

FIFOs Memory Part Context

This component belongs to the AMD '67401 series of high-speed FIFO memories. These devices were designed for applications requiring rapid data transfer between different speed domains. The series includes variations with different word widths and organizations, serving as foundational components in legacy digital electronics and industrial control systems.

FIFOs Memory Replacement Considerations

Direct substitutes may include other 64x4 asynchronous FIFOs from manufacturers like Texas Instruments or National Semiconductor. Verify pin compatibility and electrical specifications before substitution. Newer generations may offer lower power consumption or smaller packages.
