67402J

Overview

The Advanced Micro Devices 67402J is an asynchronous, uni-directional FIFO memory component organized as 64 words by 5 bits. It operates with a data rate of 10MHz and features a propagation delay of 45ns. The device is housed in a 16-CDIP package designed for through-hole mounting. It supports an operating temperature range from 0°C to 70°C.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• Uni-directional data flow architecture
• Fall-through memory organization

Applications

• Data buffering between asynchronous systems
• Interface bridging in digital logic circuits
• Temporary storage in high-speed data paths

Procurement Notes

Verify the specific suffix codes against official AMD or successor manufacturer documentation to confirm exact electrical characteristics and package variations. Ensure compatibility with existing board layouts requiring 16-CDIP through-hole mounting. Confirm temperature ratings match application requirements before procurement.

Selection Notes

Select this component when an asynchronous, uni-directional FIFO with 64x5 bit depth is required. Consider the 10MHz data rate and 45ns delay for timing constraints. Evaluate the 16-CDIP package suitability for the target PCB assembly process compared to surface-mount alternatives.

Part Context

This part belongs to the Advanced Micro Devices '67401/2' series of fall-through FIFO memories. These components were designed for high-speed data handling in legacy and industrial systems. The 67402J specifically provides the 5-bit word width variant within this family.

Replacement Considerations

Check for direct pin-compatible replacements from current manufacturers holding AMD's legacy logic portfolio. Verify that any substitute maintains the asynchronous, uni-directional functionality and 64x5 bit configuration.
