SN74ACT7201LA25DVR

FIFOs Memory Overview

The SN74ACT7201LA25DVR is an asynchronous first-in, first-out memory device manufactured by Texas Instruments. It features a memory configuration of 512 words by 9 bits, providing a total capacity of 4.5K bits. The component supports unidirectional data transfer with a maximum data rate of 28.5MHz and an access time of 25ns. It operates within a supply voltage range of 4.5V to 5.5V and is housed in a 28-pin Small Outline Integrated Circuit (SOIC) package. This integrated circuit is designed for high-speed buffering applications requiring reliable asynchronous data storage.

FIFOs Memory Feature Summary

• Asynchronous FIFO architecture enabling independent read and write clock domains
• Unidirectional data flow support for single-direction buffering tasks
• High-speed operation capability with 25ns access time and 28.5MHz data rate
• Standard 28-SOIC surface-mount packaging for compact circuit integration

FIFOs Memory Applications

• Data buffering between systems operating at different clock speeds
• Interface bridging in digital signal processing chains
• Temporary data storage in high-speed communication protocols

FIFOs Memory Procurement Notes

Verify the RoHS compliance status carefully, as sources indicate this specific variant may be non-compliant. Confirm the exact suffix 'A25' matches the required 25ns speed grade and 512x9 configuration. Ensure the 28-SOIC package type aligns with your PCB footprint requirements. Cross-reference the manufacturer's latest datasheet to validate active part status and electrical specifications before finalizing procurement orders.

FIFOs Memory Selection Notes

Select this component when unidirectional asynchronous buffering is required with moderate speed constraints. The 25ns access time suits applications not demanding sub-10ns performance. Consider the 9-bit word width for data paths requiring parity or extended bit handling. Evaluate the 28-SOIC package against available board space and thermal dissipation needs compared to alternative pinout options.

FIFOs Memory Part Context

This part belongs to the Texas Instruments SN74ACT7201 family of asynchronous FIFO memories. The family offers various memory depths including 256x9, 512x9, and 1024x9 configurations. The 'LA' designation typically indicates specific speed grades and package variations within the ACT logic series. These devices are standard solutions for decoupling data streams in mixed-signal and digital systems.

FIFOs Memory Replacement Considerations

Direct substitutes include other SN74ACT7201 variants with matching 512x9 depth and 25ns speed. Verify pin compatibility and electrical characteristics before swapping. Generic asynchronous FIFOs with similar capacities may require interface adjustments. Consult official replacement guides for equivalent parts from the same manufacturer.
