SN74ACT7813-20DL

FIFOs Memory Overview

The SN74ACT7813-20DL is a 64-word by 18-bit synchronous FIFO memory manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports clock frequencies up to 50 MHz. The device features asynchronous reset logic, independent read and write clocks, and status flags including input-ready, output-ready, half-full, and programmable almost-full/almost-empty indicators. It utilizes low-power advanced CMOS technology and is packaged in a 56-pin shrink small-outline (SSOP) format.

FIFOs Memory Feature Summary

• Supports bidirectional data buffering configuration between two devices without additional logic
• Features patented output edge control circuitry to dampen simultaneous switching noise
• Allows programming of depth offset values for the almost-full/almost-empty flag

FIFOs Memory Applications

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

FIFOs Memory Procurement Notes

Verify that the specific ordering suffix matches the required speed grade and package type. Confirm RoHS compliance and moisture sensitivity level ratings against project requirements. Ensure the component meets the specified operating temperature range for the intended environment. Cross-reference the manufacturer part number with official documentation to validate authenticity and production status before procurement.

FIFOs Memory Selection Notes

Select this component when an 18-bit wide synchronous FIFO buffer is required for system integration. Consider the 50 MHz maximum clock frequency and 12 ns access time specifications for timing constraints. Evaluate the need for bidirectional buffering capabilities or word-width expansion features inherent to the architecture. Verify compatibility with the system's power supply voltage and logic levels.
