SN74ALVC3631-20PQ

FIFOs Memory Overview

The SN74ALVC3631-20PQ is a synchronous first-in, first-out (FIFO) memory device manufactured by Texas Instruments. It provides a memory organization of 512 words by 36 bits, totaling 18 kilobits of storage capacity. The component operates at a supply voltage range typical for the ALVC logic family and supports bidirectional data transfer. It features a maximum clock frequency of 50 MHz with a propagation delay of 11.5 ns. The device is housed in a 132-pin BQFP package, measuring 24.13 mm by 24.13 mm.

FIFOs Memory Feature Summary

• Synchronous FIFO architecture supporting bidirectional data flow
• High-speed operation with 50 MHz clock capability
• Wide 36-bit data bus interface for parallel processing
• Integrated status flags for full and empty detection

FIFOs Memory Applications

• Buffering data streams between asynchronous systems
• Data rate matching in high-speed digital interfaces
• Temporary storage in communication protocol converters
• Memory buffering in video or audio signal processing chains

FIFOs Memory Procurement Notes

Verify the specific suffix -20PQ to confirm the 132-BQFP package variant. Confirm current product status as withdrawal notifications exist for related SN74ALVC36xx series parts. Ensure compatibility with 3.3 V logic levels. Check for alternative lead times due to potential obsolescence of older revisions.

FIFOs Memory Selection Notes

Select this part when a wide 36-bit synchronous buffer is required. Compare against narrower 8-bit or 16-bit FIFOs if bandwidth requirements are lower. Consider the 132-pin footprint constraints during PCB layout. Verify that the 50 MHz speed meets system timing requirements compared to faster ALVC alternatives.

FIFOs Memory Part Context

This component belongs to the SN74ALVC36xx family of synchronous FIFO memories from Texas Instruments. These devices are designed for high-performance data buffering applications requiring wide data paths. The family typically includes variants with different depths and pin counts, such as the SN74ALVC3631 series.
