SN74ACT7200L15RJ

Overview

The SN74ACT7200L15RJ is an asynchronous First-In, First-Out (FIFO) memory device manufactured by Texas Instruments. It features a storage capacity of 256 words by 9 bits, providing unidirectional data flow control. The component operates within a supply voltage range of 4.5 V to 5.5 V and utilizes the ACT logic series for high-speed performance. It is housed in a 32-pin Plastic Leaded Chip Carrier (PLCC) package with a maximum propagation delay of 15 ns.

Feature Summary

• Asynchronous FIFO architecture enabling independent read and write clock domains
• High-speed ACT logic family for reduced power consumption and faster switching
• Unidirectional data transfer capability for buffer applications

Applications

• Data buffering between microprocessors and peripheral devices
• Interface bridging between systems operating at different clock speeds
• Temporary data storage in communication protocols

Procurement Notes

Verify the specific suffix 'L15RJ' corresponds to the 15 ns speed grade and PLCC-32 package configuration. Confirm that the device meets the required 4.5 V to 5.5 V operating voltage specifications for your system design. Ensure compatibility with the asynchronous control signals such as Read, Write, Full, and Empty flags as defined in the official datasheet.

Selection Notes

Select this component when designing systems requiring asynchronous data buffering with moderate speed requirements. The 9-bit width accommodates standard byte-oriented data plus parity or status bits. Consider the PLCC-32 package constraints for PCB layout and ensure the application does not require synchronous operation or bidirectional data flow capabilities.

Part Context

This part belongs to the SN74ACT7200 series of asynchronous FIFOs from Texas Instruments. The series provides various depth and width configurations to suit different memory requirements. The ACT series offers improved performance over older TTL equivalents while maintaining pin compatibility with standard logic families.
