SN74ACT7203L25RJ

FIFOs Memory Overview

The SN74ACT7203L25RJ is an asynchronous FIFO memory IC manufactured by Texas Instruments. It features a memory organization of 2K x 9 bits, providing a total capacity of 18 kilobits. The device supports a maximum clock frequency of 28.5 MHz with a cycle time of 35 ns and a typical access time of 25 ns. It operates within a voltage range of 2 V to 6 V and is housed in a 32-pin Plastic Quad Flatpack (PQCC) package.

FIFOs Memory Feature Summary

• Asynchronous operation for independent read and write clock domains
• CMOS technology ensuring low power consumption and high noise immunity
• Integrated status flags for full and empty conditions

FIFOs Memory Applications

• Data buffering between microprocessors and peripheral devices
• Interface bridging between systems operating at different clock speeds
• Temporary data storage in digital signal processing chains

FIFOs Memory Procurement Notes

Verify the specific suffix L25RJ against the official Texas Instruments datasheet to confirm pinout compatibility and electrical characteristics. Ensure the procurement source provides valid RoHS compliance documentation if required for your assembly process. Cross-reference the package marking with the manufacturer's identification guide to prevent counterfeit components.

FIFOs Memory Selection Notes

Select this component when an asynchronous interface is required between two logic domains with independent clocks. The 9-bit word width suits applications involving byte-plus-parity or custom data widths. Consider the 2K depth for moderate buffering needs and verify that the 2V to 6V supply range matches the target system voltage levels.

FIFOs Memory Part Context

This part belongs to the SN74ACT7203 family of asynchronous FIFOs from Texas Instruments. It shares functional similarities with other members like the SN74ACT7205 but differs in memory depth and package configuration. The ACT series combines advanced CMOS technology with standard TTL-compatible inputs, offering faster switching speeds than legacy HC or HCT counterparts.

FIFOs Memory Replacement Considerations

The SN74ACT7203L25NP is a noted alternative variant within the same product line. Verify pin-to-pin compatibility and identical electrical specifications before substitution. Consult the manufacturer's latest replacement guide for any discontinued packages or updated lead-free options.
