SN74ALVC7804-40DL

FIFOs Memory Overview

The SN74ALVC7804-40DL is an asynchronous first-in, first-out (FIFO) memory device manufactured by Texas Instruments. It features an 18-bit data bus width and a storage capacity of 9 kbit, organized as 512 words by 18 bits. The component operates within a supply voltage range of 3 V to 3.6 V. It supports a maximum clock frequency of 25 MHz with an access time of 20 ns. The device utilizes low-power advanced CMOS technology and is housed in a 56-pin SSOP package.

FIFOs Memory Feature Summary

• Asynchronous operation allows independent load and unload clocks for flexible interface timing
• High-speed data processing capabilities suitable for parallel data transfer applications
• Low-power advanced CMOS technology ensures reduced current consumption during operation

FIFOs Memory Applications

• Buffering data between high-speed processors and slower peripheral devices
• Synchronizing data streams in digital communication systems
• Temporary data storage in embedded system architectures

FIFOs Memory Procurement Notes

Verify the specific suffix '40DL' against the manufacturer's official datasheet to confirm the 25 MHz speed grade and 20 ns access time specifications. Ensure the SSOP-56 package type matches the target PCB footprint requirements. Confirm RoHS compliance status through the latest production documentation before finalizing procurement orders.

FIFOs Memory Selection Notes

Select this component when asynchronous FIFO functionality is required for 18-bit wide data paths. It is appropriate for designs operating at 3.3 V logic levels where moderate speed performance is sufficient. Consider alternative synchronous variants if precise clock alignment between input and output domains is necessary for the specific application timing constraints.

FIFOs Memory Part Context

This part belongs to the SN74ALVC7804 series of 18-bit FIFOs from Texas Instruments. The series offers various speed grades and packaging options to accommodate different system performance requirements. The ALVC family is characterized by its compatibility with standard 3.3 V logic families while providing robust noise immunity and low power dissipation characteristics.

FIFOs Memory Replacement Considerations

The SN74ALVC7804-25DL is a verified substitute offering identical pinout and functionality but with a higher 40 MHz clock frequency and 18 ns access time. Verify that the faster speed grade does not introduce signal integrity issues in the existing circuit design.
