- It features asynchronous read and write operations, allowing independent clocking for input and output.
- The device includes flag logic (Empty, Full, Half-Full) to indicate FIFO status.
- It supports 9-bit wide data words, making it suitable for byte-wide data transfers with parity.
### **Features:**
- **Asynchronous FIFO Operation:** Independent read and write clocks.
- **High-Speed Performance:** 80 MHz operation with 12.5 ns access time.
- **Low Power Consumption:** CMOS technology ensures efficient power usage.
- **Flag Controls:**
- Empty Flag (EF)
- Full Flag (FF)
- Half-Full Flag (HF)
- **Expandable Depth:** Cascadable for deeper FIFO configurations.
- **Retransmit Capability:** Allows resetting the read pointer to the first word for retransmission.
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels.
- **Industrial-Grade Options:** Available for extended temperature ranges.
This FIFO is commonly used in data communication, networking, and digital signal processing applications where buffering between asynchronous systems is required.
