SN74ACT7813-20DLR

FIFOs Memory Overview

The SN74ACT7813-20DLR is a synchronous first-in, first-out memory device featuring a 64-word by 18-bit data organization. It operates within a supply voltage range of 4.5 V to 5.5 V and supports clock frequencies up to 50 MHz. The component utilizes low-power advanced CMOS technology and provides independent read and write clocks that can be asynchronous or coincident. It includes programmable almost-full/almost-empty flags and half-full status indicators.

FIFOs Memory Feature Summary

• Supports bidirectional configuration and width expansion without additional logic
• Features free-running read and write clocks for asynchronous or coincident operation
• Includes input-ready and output-ready flags synchronized to respective clocks
• Utilizes patented output edge control circuitry to dampen simultaneous switching noise

FIFOs Memory Applications

• Buffering asynchronous datapaths in high-speed digital systems
• Data rate conversion between different clock domains
• Bidirectional data buffering configurations
• Word-width expansion applications requiring 36-bit data paths

FIFOs Memory Procurement Notes

Verify the specific suffix 'DLR' against official Texas Instruments documentation to confirm package type and reel specifications. Ensure the selected variant matches the required operating temperature range of 0°C to 70°C. Confirm RoHS compliance status and moisture sensitivity level ratings prior to integration into manufacturing processes.

FIFOs Memory Selection Notes

Select this component when a 64 x 18 bit FIFO with 50 MHz maximum clock frequency is required. It is suitable for designs needing independent read and write clock domains. Consider pin-to-pin compatibility with SN74ACT7803 and SN74ACT7805 if upgrading existing architectures. Evaluate power dissipation requirements based on the specified supply current characteristics.

FIFOs Memory Part Context

This part belongs to the Widebus family of Texas Instruments logic products. It is designed for high-performance buffering applications using low-power advanced CMOS technology. The device is packaged in a shrink small-outline 300-mil SSOP format with 25-mil center-to-center spacing, providing a compact solution for dense circuit board layouts.

FIFOs Memory Replacement Considerations

The SN74ACT7813 is pin-to-pin compatible with SN74ACT7803 and SN74ACT7805. Verify functional differences regarding clock synchronization and flag behavior before substituting these parts in existing designs.
