SN74V283-7GGM

FIFOs Memory Overview

The SN74V283-7GGM 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 ×9/×18 data flow matching.
• Provides big-endian and little-endian user-selectable byte representation for data format compatibility.
• Features programmable almost-empty and almost-full flags with selectable synchronous or asynchronous timing modes.
• Enables zero-latency retransmit functionality to reread data from the FIFO without disturbing write pointers.

FIFOs Memory Applications

• Network buffering applications requiring large data storage and bus size matching.
• Video processing systems needing high-speed data buffering.
• Telecommunications equipment utilizing buffer management for unequal bus sizes.
• Data communications interfaces requiring glueless connection to DSPs.

FIFOs Memory Procurement Notes

Verify the specific suffix '7GGM' against official Texas Instruments documentation to confirm package type and temperature range. Ensure the ordering part number matches the exact datasheet revision. Confirm availability status as production data may change. Check for moisture sensitivity levels and RoHS compliance details in the latest manufacturer release notes before procurement.

FIFOs Memory Selection Notes

Select this component when designing systems that require deep, high-speed FIFO memory with independent clock domains. It is suitable for applications needing flexible bus width conversion between 9-bit and 18-bit interfaces. Consider its 5-V tolerant inputs for interfacing with different voltage logic levels. Evaluate the need for programmable flag offsets and retransmit capabilities for complex data handling requirements.

FIFOs Memory Part Context

The SN74V283 belongs to the SN74V2xx series of high-speed CMOS FIFO memories from Texas Instruments. This family includes variants with different depths such as the SN74V263, SN74V273, and SN74V293. These devices are fabricated using submicron CMOS technology and are designed for high-performance digital signal processing and data communication applications.

FIFOs Memory Replacement Considerations

Check for SN74V283 variants with different suffixes indicating package or temperature changes. Verify if SN74V273 or SN74V293 can be used if depth requirements differ. Ensure any substitute maintains the same 3.3-V operation and 166 MHz speed capability.
