SN74ALVC7813-40DLR

FIFOs Memory Overview

The SN74ALVC7813-40DLR is a low-power clocked first-in, first-out memory with a 64 x 18-bit organization. It operates from a 3-V to 3.6-V supply and supports data rates up to 25 MHz. The device features fast access times of 20 ns with a 50-pF load. It includes programmable almost-full/almost-empty flags, half-full flag, input-ready, and output-ready status indicators.

FIFOs Memory Feature Summary

• Supports asynchronous or coincident free-running read and write clocks for flexible system integration
• Enables bidirectional configuration and width expansion without requiring additional logic components
• Provides programmable depth-offset values for the almost-full/almost-empty flag via dedicated control pins

FIFOs Memory Applications

• Buffering asynchronous data paths in high-speed digital systems
• Bidirectional data buffering between different clock domains
• Word-width expansion for increasing data bus capacity

FIFOs Memory Procurement Notes

Verify the specific speed grade suffix matches the required clock frequency. Confirm the DL package variant corresponds to the shrink small-outline form factor. Ensure the operating temperature range aligns with the industrial specifications defined for this part number.

FIFOs Memory Selection Notes

Select based on the maximum clock frequency requirement, as the -40 suffix indicates a 25 MHz limit. Consider the 18-bit data width and 64-word depth for storage needs. Evaluate the need for programmable flags versus default settings when designing the control logic interface.

FIFOs Memory Part Context

This component belongs to Texas Instruments' Widebus family of low-power advanced CMOS logic devices. It is designed specifically for buffering applications where independent read and write clock domains are present. The device offers pin-to-pin compatibility within its specific functional family.

FIFOs Memory Replacement Considerations

Pin-to-pin compatible with SN74ACT7803, SN74ACT7805, and SN74ACT7813. Verify voltage level compatibility as ACT series typically operate at 4.5 V to 5.5 V compared to the ALVC 3-V to 3.6 V range.
