SN74V273-7PZA

FIFOs Memory Overview

The SN74V273-7PZA is a 16384 × 18, 3.3-V CMOS first-in, first-out (FIFO) memory fabricated using high-performance submicron technology. It operates at frequencies up to 166 MHz with a 6-ns read/write cycle time. The device features user-selectable input and output bus sizing for ×9 or ×18 configurations, supporting big-endian or little-endian byte representation. It includes independent read and write clocks, programmable almost-empty/full flags, and selectable first-word fall-through or standard timing modes.

FIFOs Memory Feature Summary

• Supports flexible bus matching with user-selectable ×9 or ×18 data flow on both input and output ports.
• Provides independent read and write clock domains allowing simultaneous reading and writing operations.
• Features programmable flag offsets that can be configured via serial or parallel methods during operation.
• Includes zero-latency retransmit capability to reread data from the FIFO without disturbing the write pointer.

FIFOs Memory Applications

• Buffering large amounts of data in network and telecommunications systems.
• Matching buses of unequal sizes in video and data communications applications.
• Glueless interface connections with Texas Instruments C6x DSPs.

FIFOs Memory Procurement Notes

Verify the specific suffix '7' against the official SN74V273 datasheet to confirm if it denotes a valid commercial variant or a restricted military/aerospace grade. Ensure the PZA package type matches the required footprint. Confirm availability status as this family may have discontinued variants.

FIFOs Memory Selection Notes

Select this component when deep memory depth of 16384 words is required alongside high-speed 166 MHz operation. Choose the SN74V273 over other family members like the SN74V263 or SN74V283 specifically for its 16384 × 18 organization. Consider the PZA TQFP package for surface-mount assembly requirements.

FIFOs Memory Part Context

This part belongs to the SN74V2xx series of high-speed 3.3-V CMOS FIFOs from Texas Instruments. The series includes SN74V263, SN74V273, SN74V283, and SN74V293, which differ primarily in memory depth. The SN74V273 specifically offers 16384 × 18 capacity, bridging the gap between the smaller SN74V263 and larger SN74V283 devices.
