SN74ALVC7813-25DLR

FIFOs Memory Overview

The SN74ALVC7813-25DLR is a low-power clocked first-in, first-out memory device from Texas Instruments. It features a 64 x 18-bit organization and operates within a 3-V to 3.6-V supply voltage range. The -25 speed grade provides a maximum data rate of 40 MHz with an access time of 15 ns under a 50-pF load. It utilizes a 56-pin shrink small-outline package.

FIFOs Memory Feature Summary

• Supports asynchronous or coincident free-running read and write clocks for flexible system integration
• Features programmable almost-full/almost-empty flags alongside half-full, input-ready, and output-ready status indicators
• Enables bidirectional configuration and word-width expansion without requiring additional logic components

FIFOs Memory Applications

• Buffering asynchronous data paths in high-speed digital systems
• Clock domain crossing applications between independent system clocks
• Data buffering in communication interfaces requiring wide bus widths

FIFOs Memory Procurement Notes

Verify the specific -25 speed grade designation to ensure compliance with the required 40 MHz maximum frequency and 15 ns access time specifications. Confirm that the procurement order specifies the DLR suffix to match the shrink small-outline surface-mount package format. Ensure the operating environment remains within the specified 0°C to 70°C temperature range during deployment.

FIFOs Memory Selection Notes

Select this component when a 18-bit wide FIFO buffer is required for 3-V logic systems. The -25 variant is appropriate for designs needing up to 40 MHz throughput. Consider pin-to-pin compatibility with SN74ACT7813 if migrating from older ACT series technologies while maintaining similar functional requirements.

FIFOs Memory Part Context

This device belongs to the Widebus family of low-power advanced CMOS products. It serves as a specialized memory solution designed for buffering asynchronous data streams. The part is functionally compatible with other members of the ALVC78xx series, offering expanded bus width capabilities compared to standard 8-bit or 16-bit alternatives.

FIFOs Memory Replacement Considerations

SN74ACT7813-25DL is a pin-compatible alternative within the same manufacturer portfolio.
