SN74V3660-10PEU

Overview

The SN74V3660-10PEU is a 3.3-V CMOS first-in, first-out (FIFO) memory with a 4096 × 36 bit organization and 576 kbit capacity. It operates at frequencies up to 166 MHz with a 6-ns read/write cycle time. The device features user-selectable bus sizing for input and output ports in widths of 36, 18, or 9 bits. It supports independent read and write clocks, big-endian/little-endian byte representation, and selectable standard or first-word fall-through timing modes.

Feature Summary

• Supports flexible bus matching with configurable input and output port widths of 36, 18, or 9 bits.
• Provides zero-latency retransmit capability and fixed low first-word latency for rapid data access.
• Includes programmable almost-empty and almost-full flags with selectable synchronous or asynchronous timing modes.

Applications

• Network buffering and packet processing
• Video signal processing systems
• Telecommunications data communications
• Signal processing applications requiring bus size matching

Procurement Notes

Verify the specific ordering suffix '-10PEU' against the manufacturer's current production data sheet to confirm package type and availability. Ensure that the required operating voltage range and temperature specifications align with the target system design before finalizing procurement.

Selection Notes

Select this component when deep memory depth combined with high-speed operation is required. It is suitable for applications needing to buffer large data volumes between buses of unequal sizes. Consider the available timing modes and flag configurations to ensure compatibility with the system's control logic requirements.

Part Context

This part belongs to the SN74V36xx series of high-speed CMOS FIFO memories from Texas Instruments. The series includes variants with different memory depths ranging from 1024 to 32768 words, all sharing a common 36-bit architecture and feature set for scalable data buffering solutions.

Replacement Considerations

Compatible substitutes within the same family include SN74V3640, SN74V3650, SN74V3670, SN74V3680, and SN74V3690. These parts share identical pinouts and functional characteristics but differ in memory depth. Verify that the alternative depth meets the application's storage requirements.
