SN74V273-7GGM

FIFOs Memory Overview

The SN74V273-7GGM is a high-speed, 3.3-V CMOS first-in, first-out (FIFO) memory fabricated using submicron technology. It provides a data organization of 16384 × 18 or 32768 × 9 bits. The device supports 166-MHz operation with a 6-ns read/write cycle time. It features independent read and write clocks, user-selectable bus sizing for matching unequal buses, and big-endian/little-endian byte representation options.

FIFOs Memory Feature Summary

• Supports flexible bus-matching configurations with selectable input and output port widths ranging from 9-bit to 18-bit.
• Offers two operational timing modes: standard mode and first-word fall-through (FWFT) mode for varying latency requirements.
• Includes programmable almost-empty and almost-full flags that can be configured via serial or parallel methods.
• Provides retransmit functionality allowing zero-latency or normal-latency rereading of previously stored data.

FIFOs Memory Applications

• Network buffering applications requiring large data storage capacity
• Video processing systems needing bus size adaptation
• Telecommunications equipment utilizing asynchronous clock domains
• Data communications interfaces demanding glueless DSP connectivity

FIFOs Memory Procurement Notes

Verify the specific suffix '7GGM' against the manufacturer's official documentation to confirm package type and availability status. Ensure the selected variant matches the required pinout and electrical specifications for your design. Cross-reference the datasheet revision date to confirm parameter validity before finalizing procurement.

FIFOs Memory Selection Notes

Select this component when designing systems that require deep memory buffers with independent read and write clock domains. Consider the SN74V273-7GGM for applications necessitating flexible bus width conversion between 9-bit and 18-bit data paths. Evaluate the FWFT versus standard mode requirements based on system latency constraints.

FIFOs Memory Part Context
