SN74V283-15GGM

FIFOs Memory Overview

The SN74V283-15GGM 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 matching. 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 between unequal buses.
• 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 the write pointer.

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 data streams.
• Data communications interfaces requiring glueless connection to DSPs.

FIFOs Memory Procurement Notes

Verify the specific suffix '15GGM' against the official datasheet to confirm package type and temperature range. Ensure the ordering code matches the exact SN74V283 variant required for your design specifications. Confirm availability through authorized distributors as lead times may vary.

FIFOs Memory Selection Notes

Select this component when designing systems that require deep, high-speed FIFO memory with independent clock domains. Consider the SN74V283 if your application demands flexible bus width configuration and programmable flag thresholds. Evaluate the need for zero-latency retransmit and FWFT mode support before finalizing the part choice.

FIFOs Memory Part Context

The SN74V283 belongs to the Texas Instruments SN74V2xx series of high-speed CMOS FIFO memories. This family includes variants with different depths such as the SN74V263, SN74V273, and SN74V293. All members share similar architectural features including 3.3-V operation and submicron CMOS technology.

FIFOs Memory Replacement Considerations

Check for SN74V283 variants with different suffixes for package or temperature differences. Verify compatibility with SN74V273 or SN74V293 only if depth requirements differ significantly. Ensure any substitute maintains the same 3.3-V supply voltage and pinout configuration.
