SN74ALVC7803-25DLR

Overview

The SN74ALVC7803-25DLR is a synchronous first-in, first-out memory device featuring a 512 x 18 bit organization and an 18-bit data bus. It operates within a 3-V to 3.6-V supply voltage range with a maximum clock frequency of 50 MHz. The component provides fast access times of 13 ns under a 50-pF load and utilizes low-power advanced CMOS technology. It is housed in a 56-pin shrink small-outline package.

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
• Features programmable almost-full/almost-empty flags alongside half-full, input-ready, and output-ready status indicators

Applications

• Buffering asynchronous data paths at high clock rates
• Bidirectional data buffering configurations
• Word-width expansion applications

Procurement Notes

Verify the specific suffix 'DLR' indicates tape-and-reel packaging when sourcing from distributors. Confirm that the operating temperature range aligns with your environmental requirements. Ensure the supply voltage strictly remains between 3 V and 3.6 V to maintain specified electrical characteristics and avoid exceeding absolute maximum ratings.

Selection Notes

Select this component for designs requiring a 512-word by 18-bit depth with independent read and write clocks. It is suitable for systems needing programmable flag offsets and bidirectional data flow capabilities. Consider the 56-pin SSOP package constraints for board space limitations compared to larger packages.
