SN74V263-7GGM

Overview

The SN74V263-7GGM is a high-speed, deep CMOS first-in, first-out (FIFO) memory fabricated using submicron technology. It features independent read and write clocks allowing simultaneous operations. The device supports user-selectable bus sizing for flexible data flow matching between ports of unequal widths. It includes programmable flags for status monitoring and offers selectable timing modes.

Feature Summary

• Supports user-selectable input and output port bus sizing for flexible data flow matching
• Features independent read and write clocks permitting simultaneous reading and writing operations
• Includes programmable almost-empty and almost-full flags with selectable offset thresholds
• Provides selectable First-Word Fall-Through or standard timing modes for data access

Applications

• Network buffering applications requiring large data storage capacity
• Video processing systems needing bus size mismatch handling
• Telecommunications equipment utilizing high-speed data transfer
• Data communications interfaces requiring glueless connection to DSPs

Procurement Notes

Verify the specific suffix '7GGM' against the manufacturer's official documentation to confirm package type and temperature range specifications. Ensure compatibility with system voltage requirements and interface standards before integration. Cross-reference ordering information with authorized distributors to confirm current availability and lead times.

Selection Notes

Select this component when deep memory depth and high-speed operation are required for buffering data streams. Consider the flexible bus-matching capabilities if interfacing systems with different data word sizes. Evaluate the programmable flag options for precise control over buffer occupancy levels in complex data paths.

Part Context

This part belongs to the SN74V263 family of 3.3-V CMOS FIFO memories. It is designed for high-performance applications requiring substantial data buffering. The family shares common architectural features but varies in memory depth and package options to suit different design constraints.

Replacement Considerations

Check for direct pin-compatible substitutes within the same logic family. Verify that alternative parts support the required bus width configurations and timing modes. Ensure electrical characteristics match the original specifications for seamless integration.
