SN74ACT7201LA25RJR

FIFOs Memory Overview

The SN74ACT7201LA25RJR is an asynchronous first-in, first-out (FIFO) memory integrated circuit manufactured by Texas Instruments. It features a storage capacity of 512 words by 9 bits, providing dual depth and width capabilities with unidirectional data flow. The device operates within a supply voltage range of 2.3 to 3.6 volts and is housed in a 32-pin JLCC package. Designed for high-speed digital applications, it supports data rates up to 80 MHz at 3.3 V. The component includes control inputs for read and write operations, enabling efficient buffering between systems operating at different clock speeds.

FIFOs Memory Feature Summary

• Asynchronous operation allows independent clock domains for input and output sections
• Unidirectional data flow simplifies interface design for single-direction communication
• Dual depth and width configuration provides flexible memory organization options
• High-speed performance supports data transfer rates up to 80 MHz

FIFOs Memory Applications

• Buffering data between microprocessors and peripheral devices
• Synchronizing data streams in telecommunications equipment
• Temporary storage in digital signal processing systems
• Interface bridging between components with different clock frequencies

FIFOs Memory Procurement Notes

Verify the complete part number including the suffix RJR to confirm tape-and-reel packaging and specific speed grade. Confirm that the 25 indicates the 3.3V operating voltage variant. Check RoHS compliance status as indicated in official documentation. Ensure the supplier provides genuine Texas Instruments products with proper traceability. Validate package type matches the 32-pin JLCC specification before procurement.

FIFOs Memory Selection Notes

Select this component when asynchronous FIFO functionality is required for 9-bit wide data paths. Consider the 512-word depth for moderate buffering needs. Verify that the 2.3-3.6V supply range matches system requirements. Evaluate pin count compatibility with PCB layout constraints for the 32-pin JLCC package. Compare propagation delay specifications against timing requirements of the target application.
