SN74V3680-10PEU

Overview

The SN74V3680-10PEU is a 3.3-V CMOS first-in, first-out (FIFO) memory with a 16384 × 36 bit organization and 576 kbit storage capacity. It operates at a maximum clock frequency of 166 MHz with a 6-ns read/write cycle time. The device features independent synchronous read and write clocks, user-selectable bus sizing for 9-bit, 18-bit, or 36-bit data paths, and big-endian/little-endian byte representation options. It includes programmable almost-empty and almost-full flags, selectable standard or first-word fall-through timing modes, and retransmit capabilities. The component is housed in a 128-pin LQFP package.

Feature Summary

• Supports flexible bus matching with configurable input and output port widths of 9, 18, or 36 bits to accommodate unequal bus sizes.
• Provides independent read and write clock domains allowing simultaneous data operations without frequency restrictions between clocks.
• Offers selectable standard timing or first-word fall-through (FWFT) modes to optimize latency for specific application requirements.
• Includes programmable almost-empty and almost-full flags with selectable asynchronous or synchronous timing modes.

Applications

• Network equipment requiring high-speed data buffering
• Video signal processing systems
• Telecommunications infrastructure
• Data communications interfaces

Procurement Notes

Verify the complete part number including the -10 speed grade and PEU package suffix against official Texas Instruments documentation. Confirm that the 166 MHz performance specification aligns with your system timing requirements. Ensure the 3.3-V supply voltage range matches your design constraints before procurement.

Selection Notes

Select this component when deep memory depth combined with wide 36-bit data paths is required. Consider the SN74V3680 series if independent clock domains and flexible bus matching are necessary. Evaluate the FWFT mode benefits if minimizing first-word latency is critical for your data flow architecture.

Part Context

This device belongs to the SN74V36xx family of high-speed CMOS FIFO memories from Texas Instruments. The family shares common architectural features but varies in memory depth. The SN74V3680 specifically provides 16384 words of storage, positioning it between the smaller SN74V3670 and larger SN74V3690 models.

Replacement Considerations

Compatible substitutes within the same family include SN74V3670 and SN74V3690. Verify pin compatibility and memory depth differences when substituting. Other speed grades such as SN74V3680-15PEU offer lower performance specifications.
