SN74V273-10PZA

Overview

The SN74V273-10PZA is a 3.3-V CMOS first-in, first-out memory with a capacity of 16384 × 18 or 32768 × 9 bits. It supports 166-MHz operation and features a 6-ns read/write cycle time. The device allows user-selectable input and output port bus sizing for flexible data flow matching. It includes big-endian/little-endian selectable byte representation and 5-V tolerant inputs.

Feature Summary

• Supports independent read and write clocks allowing simultaneous operations
• Features zero-latency retransmit capability for rereading data from the FIFO
• Includes programmable almost-empty and almost-full flags with selectable timing modes
• Provides glueless interface compatibility with specific DSP architectures

Applications

• Network buffering applications requiring large data storage
• Video processing systems needing bus size matching
• Telecommunications equipment utilizing high-speed data transfer
• Data communications interfaces managing unequal bus sizes

Procurement Notes

Verify the exact suffix against official documentation to confirm package type and temperature range. Confirm availability status as production data may change. Ensure environmental compliance details match project requirements before ordering.

Selection Notes

Select this component when deep memory depth and high-speed synchronous operation are required. Consider the flexible bus-matching capabilities if interfacing between different data widths. Evaluate the flag programming options for precise buffer management needs.

Part Context

This part belongs to the SN74V263/273/283/293 family of high-speed CMOS FIFO memories. These devices share common architectural features such as submicron CMOS technology and similar control logic structures, differing primarily in memory depth and organization configurations.

Replacement Considerations

SN74V273PZAEP is a verified substitute within the same product family offering equivalent functional specifications.
