SN74V3670-7PEU

Overview

The SN74V3670-7PEU is a 3.3-V CMOS synchronous first-in, first-out (FIFO) memory with an organization of 8192 words by 36 bits. It supports 166-MHz operation and features user-selectable input and output bus sizing for ×36, ×18, or ×9 configurations. The device includes big-endian/little-endian selectable byte representation, 5-V tolerant inputs, and independent read/write clocks.

Feature Summary

• Supports flexible bus matching on both read and write ports to accommodate unequal data sizes.
• Features fixed low first-word latency and zero-latency retransmit capabilities.
• Includes programmable almost-empty and almost-full flags with selectable timing modes.

Applications

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

Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature range. Confirm that the revision level aligns with your design specifications. Ensure all control pin states are correctly configured during master reset to establish the desired operational mode.

Selection Notes

Select this component when deep memory depth combined with high-speed data transfer is required. Consider the SN74V3670 specifically for applications needing 8192 x 36 bit capacity. Evaluate the need for variable bus widths and flag programmability before finalizing the choice.

Part Context

This part belongs to the SN74V36xx series of high-performance submicron CMOS FIFO memories. The series offers scalable depths from 1024 to 32768 words, all maintaining a consistent 36-bit width architecture and 3.3-V logic levels for system integration.

Replacement Considerations

Compatible substitutes within the same family include SN74V3640, SN74V3650, SN74V3660, SN74V3680, and SN74V3690. These parts share identical pinouts and functionality but differ in memory depth. Verify the specific word count requirement before substituting.
