SN74V283-15PZA

FIFOs Memory Overview

The SN74V283-15PZA is a 3.3-V CMOS first-in, first-out (FIFO) memory from the SN74V283 family. It provides a storage organization of 32768 × 18 or 65536 × 9 bits. The device supports 166-MHz operation with a 6-ns read/write cycle time. It features user-selectable input and output bus sizing for ×9 or ×18 data flow. The component includes big-endian/little-endian selectable byte representation and 5-V tolerant inputs.

FIFOs Memory Feature Summary

• Supports independent read and write clocks allowing simultaneous operations
• Features zero-latency retransmit capability for rereading data
• Includes programmable almost-empty and almost-full flags with selectable timing modes
• Offers flexible bus matching between unequal bus sizes

FIFOs Memory Applications

• Network buffering applications
• Video signal processing systems
• Telecommunications equipment
• Data communications interfaces

FIFOs Memory Procurement Notes

Verify the specific suffix '15' against official Texas Instruments documentation to confirm voltage grade or temperature range specifications. Ensure the PZA package type matches the target PCB footprint requirements. Confirm RoHS compliance status through current manufacturer datasheets before finalizing procurement orders.

FIFOs Memory Selection Notes

Select this component when deep FIFO depth is required for high-speed data buffering. The SN74V283 model specifically suits applications needing 32768-word capacity at 18-bit width. Consider the 166-MHz speed limit and 3.3-V supply voltage constraints during system design integration.

FIFOs Memory Part Context

This part belongs to the SN74V2xx series of high-speed CMOS FIFO memories. The series includes variants like SN74V263, SN74V273, and SN74V293, which differ primarily in memory depth and organization. All share similar control logic and interface characteristics.

FIFOs Memory Replacement Considerations

SN74V283PZ serves as a direct functional substitute within the same package family. Verify pin compatibility and electrical specifications against the original datasheet before implementation.
