SN74V273PZAEP

FIFOs Memory Overview

The SN74V273PZAEP is a 3.3-V CMOS first-in, first-out (FIFO) memory fabricated using high-performance submicron technology. It features a storage organization of 16384 x 18 or 32768 x 9 bits with a maximum clock frequency of 133 MHz and a 5 ns access time. The device operates within a supply voltage range of 3.15 V to 3.45 V and supports an extended temperature range from -55°C to +125°C. It is housed in an 80-pin LQFP package.

FIFOs Memory Feature Summary

• Supports flexible bus matching with user-selectable input and output port widths of either 9-bit or 18-bit configurations.
• Provides selectable First-Word Fall-Through (FWFT) or standard timing modes for data access control.
• Includes programmable almost-empty and almost-full flags with configurable offsets via serial or parallel methods.
• Features independent read and write clocks allowing simultaneous operations and zero-latency retransmit capability.

FIFOs Memory Applications

• Buffering large amounts of data in network applications
• Video processing systems requiring data buffering
• Telecommunications equipment interfaces
• Data communications systems matching unequal bus sizes

FIFOs Memory Procurement Notes

Verify the specific ordering suffix PZAEP to confirm the 80-pin TQFP package and extended temperature rating. Ensure compatibility with 3.3-V logic levels and check for moisture sensitivity handling requirements during assembly. Confirm that the selected variant matches the required memory depth configuration for your design.

FIFOs Memory Selection Notes

Select this component when deep FIFO buffering with high-speed 133-MHz operation is required. Consider the SN74V273PZAEP for designs needing independent read/write clocks and flexible bus width matching between 9-bit and 18-bit interfaces. Evaluate the need for programmable flag offsets and FWFT mode before choosing over standard FIFO alternatives.

FIFOs Memory Part Context

This part belongs to the SN74V273-EP series of 3.3-V CMOS FIFO memories. It shares the same functional architecture and pinout as the SN74V263, SN74V283, and SN74V293, differing primarily in memory depth. The EP designation indicates enhanced diminishing manufacturing sources support and controlled baseline production.
