Alternative Part Number

  • CY7C4235-15JC --: Pin-compatible synchronous FIFO from Cypress with similar 15 ns speed grade and 256x36 organization, widely used as a drop-in replacement for IDT72235 series.
  • SN74ACT7805-15FN --: TI synchronous FIFO with comparable depth, width and 15 ns access time, suitable functional substitute when timing margins allow.
  • 72V235L15PF --: Renesas (formerly IDT) FIFO in the 72V series offering equivalent 256x36 architecture and 15 ns speed, available as a second-source option.
