SN74ALVC7804-25DLR

FIFOs Memory Overview

The SN74ALVC7804-25DLR is an asynchronous first-in, first-out (FIFO) memory device designed for 3-V to 3.6-V VCC operation. It features a 512 x 18 organization, providing 9K bits of unidirectional data storage. The component supports a maximum clock frequency of 40 MHz with a typical access time of 18 ns. Data is written into the memory on a low-to-high transition of the load clock and read out asynchronously. This device is housed in a 56-pin SSOP package.

FIFOs Memory Feature Summary

• Asynchronous FIFO architecture enabling independent write and read clock domains
• Unidirectional data flow with 18-bit word width
• Designed for reliable operation within a 3-V to 3.6-V supply voltage range

FIFOs Memory Applications

• Buffering data between asynchronous logic systems
• Level shifting between different voltage domains
• Data rate matching in high-speed digital interfaces

FIFOs Memory Procurement Notes

Verify the specific suffix '25DLR' against the manufacturer's current ordering guide to confirm package type and tape-and-reel specifications. Ensure the required operating voltage aligns with the 3-V to 3.6-V range. Cross-reference the date code and quality grade if applicable to your production requirements. Confirm availability through authorized distributors to avoid counterfeit components.

FIFOs Memory Selection Notes

Select this component when an asynchronous FIFO with 18-bit width is required for buffering applications. It is suitable for designs operating strictly within the 3-V to 3.6-V power supply constraints. Consider the 56-pin SSOP package dimensions for PCB layout compatibility. Verify that the 40 MHz maximum clock frequency meets the system timing requirements.

FIFOs Memory Part Context

This part belongs to the Texas Instruments SN74ALVC78xx series of asynchronous FIFOs. The series offers various memory organizations and pin configurations to suit different bandwidth and interface needs. The ALVC family is characterized by low voltage operation and high speed, making it appropriate for modern portable and battery-powered electronic devices requiring efficient data management.

FIFOs Memory Replacement Considerations

Check for direct cross-reference part numbers from Texas Instruments or other manufacturers offering identical 512 x 18 asynchronous FIFO specifications. Ensure any substitute matches the 56-pin SSOP package and 3-V to 3.6-V operating voltage range. Verify pinout compatibility to prevent redesign efforts.
