C67401AN

FIFOs Memory Overview

The C67401AN is an asynchronous FIFO memory integrated circuit manufactured by Advanced Micro Devices. It features a memory organization of 64 x 4 bits and supports cascading for expanded width configurations. The device operates within a supply voltage range of 4.75 V to 5.25 V, with a maximum supply current of 170 mA. Key electrical specifications include an access time of 40 ns and a data rate of 15 MHz. It is designed for through-hole mounting in a 16-DIP package and functions within an operating temperature range of 0°C to 70°C.

FIFOs Memory Feature Summary

• Asynchronous operation for flexible interface integration
• Cascadable architecture supporting 64 x 4 or 64 x 5 bit configurations
• Uni-directional bus directionality

FIFOs Memory Applications

• General-purpose buffer memory applications
• Data rate matching between asynchronous systems
• Temporary storage in digital logic circuits

FIFOs Memory Procurement Notes

Verify the manufacturer designation as Advanced Micro Devices, noting historical corporate acquisitions may affect branding on legacy components. Confirm the specific suffix 'AN' corresponds to the 16-DIP through-hole package variant. Ensure the operating temperature range meets system requirements, as this part is specified for commercial temperatures (0°C to 70°C). Cross-reference datasheet revisions to confirm pinout compatibility if integrating into existing designs.

FIFOs Memory Selection Notes

Select this component when an asynchronous FIFO with a 64-word by 4-bit depth is required. It is suitable for applications needing simple, unidirectional buffering without complex control interfaces. Consider the 16-DIP package for prototyping or through-hole manufacturing processes. Evaluate the 40 ns access time against system clock speeds to ensure adequate timing margins for the target application frequency.

FIFOs Memory Part Context

The C67401 belongs to the family of first-in-first-out (FIFO) memory devices produced by Advanced Micro Devices. These components are designed to handle data transfer between systems operating at different speeds or with different clock domains. The C67401 specifically offers a compact solution for small buffer requirements, utilizing standard TTL-compatible logic levels for ease of integration into broader digital systems.
