SN74ACT7200L25DV

Overview

The SN74ACT7200L25DV is an asynchronous FIFO memory device manufactured by Texas Instruments. It provides a storage capacity of 2,256 bits organized as 256 words by 9 bits. The component operates with a unidirectional data flow and supports a maximum clock frequency of 28.5 MHz. Typical access time is specified at 25 ns. It functions within a supply voltage range of 2 V to 6 V and is housed in a 28-pin SOIC package.

Feature Summary

• Asynchronous operation allows independent read and write clock domains for flexible interface integration.
• Unidirectional data transfer simplifies system design for single-direction buffering applications.
• Wide operating voltage range supports compatibility with various logic families and power supplies.

Applications

• Data buffering between microprocessors and peripheral devices
• Interface bridging between systems with different clock speeds
• Temporary data storage in high-speed digital communication links

Procurement Notes

Verify the exact suffix 'DV' corresponds to the 28-SOIC package and commercial temperature grade. Confirm RoHS compliance status if required for specific manufacturing standards. Ensure the ordering part number matches the specific pinout and electrical characteristics defined in the official Texas Instruments datasheet for this variant.

Selection Notes

Select this component when asynchronous buffering is required for 9-bit wide data paths. Consider the 28.5 MHz speed limit and 25 ns access time against system timing requirements. Evaluate the 2 V to 6 V supply range to ensure compatibility with the target circuit's voltage levels. Verify that the unidirectional nature meets the application's data flow needs without requiring bidirectional control logic.

Part Context

This part belongs to the SN74ACT series of advanced CMOS logic components from Texas Instruments. The ACT series offers performance comparable to LS TTL but with lower power consumption and wider voltage tolerance. As a FIFO memory device, it serves as a critical interface element in digital systems requiring temporary data storage and synchronization between asynchronous domains.

Replacement Considerations

Check for direct pin-compatible alternatives such as other SN74ACT7200 variants with different package options or speed grades. Verify that any substitute maintains the same 256x9 organization and asynchronous functionality. Ensure electrical parameters like access time and supply voltage ranges meet or exceed the original specifications.
