SN74ACT72231L35RJ

FIFOs Memory Overview

The SN74ACT72231L35RJ is a synchronous first-in, first-out (FIFO) memory device manufactured by Texas Instruments. It features a memory organization of 2K x 9 bits, providing a total capacity of 18 kilobits. The component operates at a supply voltage of 5V and utilizes an ACT logic family for performance. It is housed in a 32-lead Plastic Quad Flat Package (PQCC32), also identified as LCC-32. The device supports synchronous data transfer with dedicated read and write clock inputs.

FIFOs Memory Feature Summary

• Synchronous FIFO architecture with independent read and write clocks
• High-speed data storage and retrieval capabilities
• Compatible with standard 5V logic systems

FIFOs Memory Applications

• Buffering data streams between asynchronous or synchronous domains
• Data storage in high-speed digital communication interfaces
• Temporary memory holding in microprocessor-based systems

FIFOs Memory Procurement Notes

Verify the package type PQCC32 matches your PCB footprint requirements. Confirm the operating temperature range aligns with commercial specifications. Ensure the 5V supply voltage is stable within datasheet limits. Check RoHS compliance status if environmental regulations apply to your assembly process.

FIFOs Memory Selection Notes

Select this component when a 2Kx9 synchronous FIFO is required for 5V applications. Consider the PQCC32 package constraints during layout design. Evaluate timing parameters against system clock speeds. Compare pin compatibility with existing designs using the base 74ACT72231 series.

FIFOs Memory Part Context

This part belongs to the Texas Instruments SN74ACT72231 series of synchronous FIFO memories. It shares functional characteristics with other variants in the family but differs in speed grade and packaging. The L35 suffix typically denotes specific electrical or mechanical attributes defined by the manufacturer for this particular revision.

FIFOs Memory Replacement Considerations

Check for direct substitutes within the 74ACT72231 family that offer compatible pinouts and electrical specifications. Verify that alternative packages maintain the same footprint dimensions. Ensure any replacement maintains synchronous operation and 5V compatibility.
