SN74V283-6GGM

FIFOs Memory Overview

The SN74V283-6GGM is a 3.3-V CMOS first-in, first-out (FIFO) memory with a capacity of 32768 × 18 bits. 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 widths of ×9 or ×18, supporting flexible data flow configurations. It includes big-endian/little-endian selectable byte representation, 5-V tolerant inputs, and independent read and write clocks for simultaneous operations.

FIFOs Memory 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 programmable almost-empty and almost-full flags with selectable timing modes.
• Enables zero-latency retransmit functionality for rereading data from the FIFO.

FIFOs Memory 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 requiring glueless connection to DSPs.

FIFOs Memory Procurement Notes

Verify the specific suffix '6GGM' against the official datasheet to confirm package type and temperature range. 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 pinout for the GGM package.

FIFOs Memory Selection Notes

Select this component when deep memory depth and high-speed operation are required. Consider the SN74V283 family if independent read/write clocks and flexible bus matching are necessary. Evaluate the need for programmable flags and retransmit capabilities before choosing over simpler FIFO alternatives.

FIFOs Memory Part Context

The SN74V283 belongs to a family of high-speed CMOS FIFO memories including the SN74V263, SN74V273, and SN74V293. These devices share similar architectural features but differ in memory depth. The SN74V283 specifically offers 32768 × 18 bit organization, positioned between the smaller SN74V273 and larger SN74V293 in terms of capacity.

FIFOs Memory Replacement Considerations

Direct substitutes within the same family include SN74V263, SN74V273, and SN74V293, provided memory depth differences are acceptable. Verify pin compatibility and electrical specifications before substitution.
