SN74ALVC7813-25DL

FIFOs Memory Overview

The SN74ALVC7813-25DL is a low-power clocked first-in, first-out memory device featuring a 64 x 18 bit organization. It operates from a 3-V to 3.6-V supply voltage and supports data rates up to 40 MHz with a maximum access time of 15 ns under a 50-pF load. The component utilizes independent read and write clocks that can be asynchronous or coincident. It includes programmable almost-full/almost-empty flags, half-full flag, input-ready, and output-ready status indicators. The device is packaged in a 56-pin shrink small-outline package.

FIFOs Memory Feature Summary

• Supports bidirectional configuration and width expansion without additional logic
• Features programmable almost-full/almost-empty depth-offset values
• Provides asynchronous reset capability synchronized to independent system clocks

FIFOs Memory Applications

• Buffering asynchronous data paths
• Bidirectional data buffering configurations
• Word-width expansion applications

FIFOs Memory Procurement Notes

Verify the specific suffix '25' indicates the 40 MHz speed grade against the official datasheet specifications. Confirm the DL package designation corresponds to the 56-pin SSOP form factor. Ensure the operating temperature range meets the application requirements for the commercial grade variant.

FIFOs Memory Selection Notes

Select this component when a 18-bit wide FIFO buffer is required within a 3-V to 3.6-V power domain. The device is suitable for systems needing independent read and write clock domains. Consider the pin-to-pin compatibility with older ACT series devices if migrating existing designs.

FIFOs Memory Part Context

This part belongs to Texas Instruments' Widebus family of low-power advanced CMOS logic products. It serves as a direct functional replacement for the SN74ACT7813 in terms of pinout and logical operation, offering improved power consumption characteristics while maintaining compatible interface standards for legacy system integration.

FIFOs Memory Replacement Considerations

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