Alternative Part Number

  • CY7C4255-35PC --: Pin-compatible synchronous FIFO with similar 35 ns speed grade and 8K x 18 organization, widely used as a drop-in replacement for IDT 72225 series.
  • SN74ACT7805-35PN --: Equivalent 8K x 18 synchronous FIFO from TI's ACT FIFO family, matching the 35 ns access time and standard pinout for IDT72225 sockets.
  • 72V225L35PF --: Renesas (formerly IDT) 3.3V 8K x 18 synchronous FIFO with 35 ns speed, functionally equivalent and available as a direct replacement in the same package.
