- **Low Power Consumption:** Optimized for 3.3V operation  
- **Programmable Flags:** Almost Full/Almost Empty indicators  
- **Retransmit Function:** Allows data to be re-read without external logic  
- **5V-Tolerant Inputs:** Ensures compatibility with mixed-voltage systems  
- **Expandable Data Width:** Supports 18-bit to 36-bit configurations  
- **Industrial-Grade Options Available** (though this specific model is commercial)  

This FIFO is commonly used in networking, telecommunications, and data processing applications requiring high-speed buffering.

Application Scenarios & Design Considerations

CMOS DUAL SyncFIFO DUAL 256 x 18, DUAL 512 x 18, DUAL 1,024 x 18, DUAL 2,048 x 18, and DUAL 4,096 x 18

Alternative Part Number

  • CY7C4255V-15AXC --: Cypress synchronous FIFO in the same 15 ns speed grade and comparable 8Kx18 density, pin-compatible with the IDT 72825 family and widely available as a drop-in alternative.
  • SN74ACT7808-15PAG --: TI 15 ns synchronous FIFO with similar organization and timing, suitable functional replacement when the IDT part is unavailable.
  • 72V825L15PF --: Renesas FIFO with matching 15 ns access time and equivalent 8Kx18 architecture, offering a second-source option for the IDT 72825 series.
  • 72V255L15PF --: Renesas 72V255 series FIFO offers equivalent 8K x 18 architecture and 15 ns speed, serving as a direct functional substitute for the IDT 72825 family.
