Application Scenarios & Design Considerations

CMOS SyncFIFOO 256 x 18, 512 x 18, 1024 x 18, 2048 x 18 and 4096 x 18

Alternative Part Number

  • CY7C4235-25JC --: Pin-compatible synchronous FIFO from Cypress with similar 25 ns speed grade and 4K x 18 organization, widely used as a drop-in replacement for IDT 72235 series.
  • SN74ACT7805-25PN --: TI synchronous FIFO with comparable depth, width and 25 ns access time, suitable functional alternative when IDT parts are unavailable.
  • 72V235L25PF --: Renesas (formerly IDT) 3.3V synchronous FIFO in the same 72235 family architecture with 25 ns speed, offering equivalent functionality from the successor vendor.
