72V2x5 Functional Block Diagram
Description
The 72V245 is a 4K x 18 first-in, first-out (FIFO) memory with clocked read and write controls. It is a 3.3V version of the 72245 FIFO and is applicable for a wide variety of data buffering needs, such as optical disk controllers, Local Area Networks (LANs), and interprocessor communication. It has 18-bit input and output ports. The Read Clock (RCLK) can be tied to the Write Clock for single-clock operation, or the two clocks can run asynchronously of one another for dual-clock operation.
