SN74ALVC7805-25DLR

FIFOs Memory Overview

The SN74ALVC7805-25DLR is a synchronous first-in, first-out (FIFO) memory device manufactured by Texas Instruments. It features an organization of 256 words by 18 bits, providing a total storage capacity of 4.5 Kbits. The component supports a maximum data rate of 25 MHz and has a typical access time of 20 ns. It operates on a single power supply voltage ranging from 3 V to 3.6 V. The device utilizes a unidirectional bus configuration and is housed in a 56-pin BSSOP package.

FIFOs Memory Feature Summary

• Synchronous FIFO architecture with programmable flags for status monitoring
• Wide data bus width supporting 18-bit parallel data transfer
• Single-supply operation compatible with standard low-voltage logic levels

FIFOs Memory Applications

• Buffering data streams between asynchronous clock domains
• Temporary storage in high-speed digital signal processing chains
• Interface bridging in communication systems requiring data alignment

FIFOs Memory Procurement Notes

Verify the specific suffix '25' indicates the speed grade corresponding to the 25 MHz data rate and 20 ns access time. Confirm the 'DLR' suffix denotes the tape and reel packaging format. Ensure the design accommodates the specified 3 V to 3.6 V operating range. Check for RoHS compliance status as per current manufacturing standards.

FIFOs Memory Selection Notes

Select this component when an 18-bit wide synchronous FIFO is required for buffering applications. It is suitable for designs needing a depth of 256 words with a 25 MHz operational limit. Consider the 56-pin SSOP package constraints for PCB layout. Verify that the system power supply remains within the 3 V to 3.6 V window for reliable operation.

FIFOs Memory Part Context

This part belongs to the SN74ALVC7805 series of synchronous FIFOs. It shares architectural similarities with other members like the SN74ALVC7804 but offers wider data paths. The ALVC series is characterized by low voltage operation and high-speed performance, making it distinct from older ACT or HC families.

FIFOs Memory Replacement Considerations

Direct replacements may include other SN74ALVC7805 variants with different speed grades or packaging options. Cross-referencing with SN74ACT7805 is possible if 5 V operation is acceptable, though electrical characteristics will differ significantly.
