SN74V263-10PZA

Overview

The SN74V263-10PZA is a high-speed, 3.3-V CMOS first-in, first-out (FIFO) memory fabricated using submicron technology. It provides a storage capacity of 8192 × 18 bits or 16384 × 9 bits. The device supports independent read and write clocks operating up to 166 MHz with a 6-ns cycle time. It features user-selectable bus sizing for flexible data flow matching between ports.

Feature Summary

• Supports user-selectable input and output port bus sizing for flexible data flow matching
• Provides big-endian and little-endian user-selectable byte representation
• Features zero-latency retransmit capability for rereading previously accessed data
• Includes programmable almost-empty and almost-full flags with selectable timing modes

Applications

• Network buffering applications requiring large data storage
• Video processing systems needing bus size matching
• Telecommunications equipment utilizing unequal bus interfaces
• Data communications systems interfacing with DSPs

Procurement Notes

Verify the specific ordering suffix matches the required package type before procurement. Confirm that the voltage specifications align with the target system requirements. Ensure compatibility with existing logic levels and clock frequencies. Review the datasheet for any recent production changes or pinout updates.

Selection Notes

Select this component when deep FIFO memory depth is required alongside high-speed operation. Consider the SN74V263 for applications needing flexible bus width conversion between 9-bit and 18-bit interfaces. Evaluate the need for programmable flag offsets and retransmit functionality during system design.

Part Context
