FIFOs Memory Procurement Notes

Verify the specific suffix '15' against the manufacturer's current datasheet to confirm the exact speed grade and timing characteristics. Confirm the 132-pin BQFP package availability as this variant may be subject to discontinuation or lifecycle changes. Ensure compatibility with 4.5V to 5.5V power domains during integration.

FIFOs Memory Selection Notes

Select this component when designing systems requiring wide 36-bit synchronous FIFO buffers. It is suitable for applications needing bidirectional data flow with a depth of 64 words. Consider the 15 ns access time and 33.4 MHz clock limit for timing closure. Verify that the 132-pin BQFP footprint fits the PCB layout constraints.

FIFOs Memory Part Context

This part belongs to the SN74ABT3611 series of synchronous FIFO memories.
