SN74V3690-6PEU

The SN74V3690-6PEU is a synchronous FIFO from Texas Instruments in an LQFP-128 package. Organized as 32Kx36, it runs on a 6 ns cycle for 166 MHz clocking from a 3.15 V to 3.45 V supply over 0 C to +70 C, and it supports bus matching between x36, x18 and x9 widths. The wide 36-bit path with built-in width conversion is the selection point: it links wide processor or network buses to narrower peripherals through one buffer, which removes separate width-conversion logic in high-throughput networking, imaging and test equipment. Selection advice: choose this code when the design genuinely moves 36-bit words or needs the bus-matching function; for plain x18 buffering at similar speed, the SN74V293 group is the simpler fit. Confirm the LQFP-128 (PEU) footprint in your layout library, as package codes in this family are not interchangeable. Parameters verified against Texas Instruments documentation.
