SN74ACT7201LA20DV

FIFOs Memory Overview

The SN74ACT7201LA20DV is a high-speed asynchronous FIFO memory device manufactured by Texas Instruments. It features an organization of 36 words by 18 bits, providing a total storage capacity of 648 bits. The component operates within a supply voltage range of 4.5 V to 5.5 V and utilizes the ACT logic series for enhanced performance. It supports unidirectional data transfer with asynchronous control signals, including read and write enable inputs. The device is housed in a 40-pin SSOP package, suitable for surface-mount applications requiring compact footprints.

FIFOs Memory Feature Summary

• Asynchronous operation allows independent clock domains for reading and writing data without synchronization requirements.
• High-speed CMOS technology ensures low power consumption while maintaining fast access times for data retrieval.
• Dedicated status flags indicate full and empty conditions to manage buffer flow effectively.

FIFOs Memory Applications

• Data buffering between microprocessors and peripheral devices operating at different speeds
• Interface bridging in communication systems requiring temporary data storage
• Digital signal processing pipelines for smoothing data throughput variations

FIFOs Memory Procurement Notes

Verify the specific suffix '20DV' against the official Texas Instruments datasheet to confirm pinout compatibility and electrical characteristics. Ensure the procurement source provides valid RoHS compliance documentation. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the SSOP-40 package matches your PCB footprint requirements before finalizing orders.

FIFOs Memory Selection Notes

Select this component when designing systems that require decoupling of data generation and consumption rates using asynchronous logic. The 18-bit word width suits applications needing wider data paths than standard 8-bit or 16-bit FIFOs. Consider the ACT series speed and power trade-offs compared to AC or HC families. Verify that the 4.5 V to 5.5 V operating range aligns with your system's power supply rails.

FIFOs Memory Part Context

This part belongs to the SN74ACT7201 family of asynchronous FIFO memories. It shares functional similarities with other members like the SN74ACT7201L but differs in packaging and specific speed grades. The family is designed for general-purpose digital logic applications requiring reliable data storage and retrieval. It complements Texas Instruments' broader portfolio of logic ICs and memory solutions.

FIFOs Memory Replacement Considerations

Compatible substitutes include the IDT7201LA and QS7201A. Verify pin compatibility and timing parameters before substitution. The SN74ACT7201LA20DV may be replaced by equivalent parts from Integrated Device Technology or Quality Semiconductor if sourcing constraints exist.
