166 MHz synchronous FIFO with configurable depth
The SN74V293-6PZA is a 1.125 Mbit synchronous FIFO from the 74V series, clocked at 166 MHz with a 4.5 ns access time — the read-cycle floor is set by this access time, not the clock period, so back-to-back reads at full clock rate require the output enable to settle within one cycle. Memory is configurable as 64K x 18 or 128K x 9 via the width-expansion pin, giving the system architect a single BOM entry that serves either a 9-bit or 18-bit data path without a board spin. First-word fall-through (FWFT) mode presents the first written word on the output bus without a read request — this cuts the initial latency to zero for streaming data paths where the first sample must arrive immediately after the write strobe.
80-LQFP footprint and board-fit
The tray package is the factory-standard delivery format for this part; no reel or tape option is listed, so volume pick-and-place lines should budget a tray feeder or a bulk-to-reel conversion step.
Active lifecycle and compliance
ROHS3 compliant per the manufacturer's declaration — no exemption-based conflicts with EU RoHS recast (Directive 2015/863).
