SN74ACT7200L20RJ

Overview

The SN74ACT7200L20RJ is an asynchronous FIFO memory IC manufactured by Texas Instruments. It provides a storage capacity of 256 words with a 9-bit data width, organized as 256x9 configuration. The device utilizes the ACT logic series for performance. It is housed in a 32-pin Plastic Quad Flat Package (PQCC32), also identified as LCC-32. This component serves as a buffer between systems operating at different speeds or protocols.

Feature Summary

• Asynchronous operation allows independent clock domains for read and write ports
• Provides 256-word by 9-bit data storage capacity
• Utilizes ACT logic technology for high-speed performance

Applications

• Data buffering between microprocessors and peripheral devices
• Interface bridging between systems with different clock frequencies
• Temporary data storage in communication protocol converters

Procurement Notes

Verify the package type PQCC32/LCC-32 matches your PCB footprint requirements. Confirm the 256x9 depth and width specifications align with system memory needs. Ensure voltage levels are compatible with your design constraints before procurement.

Selection Notes

Select this part when asynchronous FIFO functionality is required with ACT speed grades. The 9-bit width accommodates standard byte-oriented data with parity or error checking bits. Consider the 32-pin LCC package for surface mount assembly compatibility.

Part Context

This component belongs to the Texas Instruments SN74ACT family of logic devices. It is categorized under FIFOs and Memory ICs. The ACT series offers improved switching speeds compared to older HC or HCT families while maintaining CMOS power consumption characteristics.

Replacement Considerations

Check for pin-compatible alternatives within the SN74ACT7200 series. Verify that substitute parts maintain the same 256x9 depth and asynchronous operation mode. Ensure the replacement supports the PQCC32 package if board space is constrained.
