SN74ACT2227DWR

FIFOs Memory Overview

The SN74ACT2227DWR is a synchronous dual FIFO memory device manufactured by Texas Instruments. It features two independent 256x1 bit memory banks, providing a total storage capacity of 512 bits. The component operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 60 MHz with an access time of 9 ns. It utilizes a 28-pin SOIC package for surface mount installation and functions across an industrial temperature range from -40°C to +85°C.

FIFOs Memory Feature Summary

• Provides dual independent 256x1 bit synchronous FIFO memory structures
• Supports unidirectional data transfer operations
• Enables high-speed data buffering with 60 MHz clock frequency capability

FIFOs Memory Applications

• High-speed data buffering in digital communication systems
• Interface bridging between asynchronous logic domains
• Data rate matching in embedded processing architectures

FIFOs Memory Procurement Notes

Verify the specific suffix 'DWR' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the 28-SOIC footprint matches the target PCB design constraints. Ensure the operating environment remains within the specified -40°C to +85°C temperature limits to maintain guaranteed performance specifications.

FIFOs Memory Selection Notes

Select this component when dual-channel synchronous buffering is required for 1-bit wide data paths. The ACT series offers faster switching speeds compared to standard HCT or HC logic families. Verify that the 60 MHz maximum clock frequency meets the system timing requirements and that the 9 ns access time aligns with the application latency constraints.

FIFOs Memory Part Context

This part belongs to the SN74ACT2227/2229 family of synchronous FIFO memories. These devices are designed to handle data flow control in complex digital systems where temporary storage and synchronization are critical. The dual-bank architecture allows for flexible configuration of memory resources within a single integrated circuit package.

FIFOs Memory Replacement Considerations

The SN74ACT2229DWR serves as a functional substitute within the same product family, offering identical electrical characteristics and pinout compatibility.
