SN74ACT72231L25RJ

FIFOs Memory Overview

The SN74ACT72231L25RJ is a synchronous first-in, first-out (FIFO) memory integrated circuit manufactured by Texas Instruments. It features a memory organization of 2K x 9 bits, providing a total capacity of 18 kilobits. The device operates with a unidirectional data flow and utilizes an Advanced CMOS (ACT) logic family for performance. It is housed in a 32-lead Plastic Leaded Chip Carrier (PLCC) package, specifically designated as LCC-32. The component is designed for high-speed digital applications requiring temporary data storage and buffering.

FIFOs Memory Feature Summary

• Synchronous operation with dedicated clock input for precise data timing control
• Unidirectional data transfer architecture simplifying interface design
• Advanced CMOS technology ensuring low power consumption and high noise immunity

FIFOs Memory Applications

• Data buffering in high-speed digital communication systems
• Temporary storage in microprocessor-based data acquisition systems
• Interface matching between devices operating at different clock speeds

FIFOs Memory Procurement Notes

Verify the specific suffix 'L25RJ' corresponds to the PLCC-32 plastic package and bulk packaging configuration. Confirm the manufacturer is Texas Instruments. Ensure the part status is active before procurement. Cross-reference the datasheet for exact electrical specifications and pinout definitions to avoid compatibility issues with existing designs.

FIFOs Memory Selection Notes

Select this component when a synchronous FIFO with 9-bit word width and 2048-word depth is required. Consider the ACT series characteristics for speed and power balance. Verify that the 32-pin PLCC package fits the PCB layout constraints. Ensure the system voltage levels are compatible with the ACT logic family specifications provided in the official datasheet.

FIFOs Memory Part Context

This part belongs to the SN74ACT series of advanced CMOS logic devices from Texas Instruments. The SN74ACT72231 is a specific variant within the FIFO memory category. It is distinct from asynchronous FIFOs and other bit-width configurations in the same family. The device represents a standard solution for buffering needs in industrial and commercial electronic equipment.

FIFOs Memory Replacement Considerations

Check for direct substitutes such as the SN74ACT72231N or other variants with different package types like SOIC if leaded chip carrier availability is limited. Verify pin-to-pin compatibility and identical electrical parameters before substitution.
