SN74V283-10PZA

FIFOs Memory Overview

The SN74V283-10PZA 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 and features a 6-ns read/write cycle time. The device supports user-selectable bus sizing for both input and output ports, allowing configurations of ×9 or ×18 bits. It includes big-endian/little-endian selectable byte representation, 5-V tolerant inputs, and independent read and write clocks.

FIFOs Memory Feature Summary

• Supports flexible bus matching with user-selectable input and output port widths of either 9-bit or 18-bit.
• Provides big-endian and little-endian user-selectable byte representation for data formatting flexibility.
• Features programmable almost-empty and almost-full flags with selectable synchronous or asynchronous timing modes.
• Includes zero-latency retransmit capability and fixed low first-word latency for efficient data buffering.

FIFOs Memory Applications

• Network equipment requiring large data buffering
• Video processing systems needing bus size matching
• Telecommunications infrastructure applications
• Data communications interfaces

FIFOs Memory Procurement Notes

Verify the specific suffix '10' against official Texas Instruments documentation 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 pinout alignment with the 80-pin TQFP package before integration.

FIFOs Memory Selection Notes

Select this component when deep FIFO depth is required alongside high-speed operation up to 166 MHz. Consider its independent clock domains for asynchronous interface bridging. Evaluate its programmable flag offsets if precise buffer management thresholds are necessary for the application design.

FIFOs Memory Part Context

This part belongs to the SN74V2xx series of high-speed CMOS FIFOs from Texas Instruments. The family shares common architectural features including submicron CMOS technology and glueless DSP interfacing capabilities. Variations within the series differ primarily in memory depth and organization.
